Chapter One: introduction

 

International economics nowadays plays an essential role in the researches of the economic growth and development. The performance of international economic activities in general and trade activities in particular of a country can have a significant impact on the whole economy's performance.

There have been many studies of the trade performance and trade balance. The imbalance of trade, i.e. the surplus (excess of export over import) and deficit (excess of import over export) is often seen as a problem. In general, persistent trade deficit may do harm to the economy, since trade deficit leads to foreign exchange gap and foreign exchange scarcity. This will lower the country's position in international payment. Therefore, improving trade balance or reducing its deficit is raised as a big matter to the policy-making for a sound economy.

Economic studies show many approaches to improving trade balance. Among the variables having effect on trade balance such as domestic GDP, foreign income, commodity prices and exchange rate, exchange rate is regarded as an important factor, since it significantly affects exports and imports of a country.

In theory, depreciation of real exchange rate will increase export and decrease import, thus improving trade balance. As a result, in policy terms, devaluation is often used as a good instrument suggested by IMF stabilization program for improving trade balance for countries suffered from trade deficits. However, in practice, the result is still ambiguous and mixed. Some countries succeeded in improving trade balance by devaluation, but some not.

In Vietnam, the exchange rate regime has been really a problem. Since 1993, Vietnam has continuously suffered from large trade deficits, after the only surplus in 1992. During 1993-1996, the nominal exchange rate was relatively stable while the real exchange rate is seen appreciated[1]. The competitiveness of exports may reduce in line with the increase in real exchange rate.

Especially since 1997, Vietnam has suffered from appreciation of its exchange rate in comparison with those of its major trade partners. The reason is that the financial crisis in East Asia forced affected countries to float their exchange rates with sharp depreciation of exchange rate  (from 20 per cent to 80 per cent in terms of US dollar). As a result, trade balances in these countries in 1998 were improved[2]. But the problem is that exports did not clearly increase. One reason for improving trade balance was the decline in imports due to lower domestic income and corporate restructuring, and the implementation of other trade policies to restrict imports.

Since 1994, debate on whether Vietnam should take devaluation is still in question and some economists have asked for devaluation. Vu Ngoc Nhung (1994) and another author in Vietnam Banking Review (1998) called devaluation an effective instrument to improve trade balance. Besides, Le Viet Duc (1995), Nguyen Thi Hien (1995) and Truong Xuan Le (1995) argued that devaluation is not a solution for exports promotion and trade improvement. Recently, some quantitative analysis in trade balance and devaluation tried to determine a clearer relationship between trade balance and exchange rate. However, the answers are still mixed. In addition, the significance of coefficients is low. In some regressions, there are problems in econometrics specification.

This thesis attempts to analyze Vietnam's trade balance and the impact of exchange rate changes to Vietnam's competitiveness and trade (exports and imports), including quantitative analysis. The thesis will give answers to the following questions:

·        How is the performance of trade (exports, imports and balances) in Vietnam during 1989-1998?

·        Whether the real exchange rate in Vietnam has been overvalued and how did the real exchange rate affect trade balance, and the structure of trade?

·        What are policy implications for improving trade balance?

The remainder of the thesis is as follows: Chapter Two is about the theoretical framework on trade balance, exchange rate and the relationship between exchange rate and trade (exports and imports), including theories and empirical evidences from some countries. Chapter Three will review Vietnam's economy in the period 1989-1998 and its major economic reforms, especially in trade. From the economic and trade performance and the analysis of factors of exports and imports, there will be some derivations about the relationship between trade and exchange rate. And then, in chapter Four, the quantitative analysis will check whether or not trade and exchange rate (both nominal exchange rate and real exchange rate) have any relationship. From the findings in chapter Three and chapter Four, some policy recommendations will be withdrawn in chapter Five, which will be the conclusion for the thesis. Further explanations for the research will be seen in the Appendix.

 

Chapter Two: theoretical framework

I- Definitions and theoretical framework

I.1. Definitions

Trade balance[3] shows a summary of a country's trading activities, including exports (sales of domestically produced goods and services to the rest of the world) and imports (expenditure of goods and services bought from the rest of the world). Trade balance is the difference between the country's value of exports and value of imports. Trade balance may be surplus or deficit. A surplus of trade balance is the excess of exports over imports of goods. A deficit of trade balance is the excess of imports over exports of goods.

Exchange rate is the price of one country's currency in terms of another’s. In this thesis, exchange rate is defined as the units of domestic currency per unit of foreign currency (e.g VND/1 USD). The effects and  implications of exchange rate are measured by nominal, real and effective exchange rate.

The nominal exchange rate is merely the price of one currency in terms of another’s with no reference made to what this means in terms of purchasing power of goods/services.

The real exchange rate is the nominal exchange rate adjusted for relative prices between the countries under consideration. RER =  NER x Pf/Pd

(where: RER is the real exchange rate, NER is nominal exchange rate, Pd is the domestic price, and Pf is the foreign price). When RER rises, there is real depreciation of domestic currency relatively to foreign currency. When the RER falls, there is real appreciation of domestic currency.

Real effective exchange rate is the real exchange rate adjusted by a basket of exchange rate: REER = å WiRERI .­(Where REER is the real effective exchange rate adjusted by the basket of real exchange rate RERi of the traded countries weighted with its share in trade Wi).  REER is often considered as a more useful measure for a country's competitiveness in the trade with the whole world but not a single country, because it measures the competitiveness of a country in the world of many countries.

In reality, there are several types of exchange rate regime which define how exchange rate works. The two typical ones are fixed exchange-rate system and floating exchange rate system.

Under a float exchange rate system, the exchange rate is free to fluctuate day by day and will fall or rise in line with changing market conditions, serving to keep a country's balance of payments more or less in equilibrium on a continuing basis. When exchange rate increases or decreases, export and import will change accordingly, and so the trade balance changes.

Under a fixed exchange rate system, the exchange rates once established will remain unchanged for relatively long period. If the exchange rate gets too far out of line with underlying market, the exchange rate can be refixed at a new value, which makes imports and exports changes accordingly.

When exchange rate is refixed, it is the case of devaluation or revaluation policies. Devaluation and revaluation refer to adjustments in fixed exchange rate regime. If the exchange rate peg[4] is increased, the price of foreign currency in terms of domestic currency is increased and the domestic currency is said to be devalued. If the exchange rate peg is decreased, the domestic currency price of foreign currency is decreased, and is said to be revalued.

In the real world, nominal exchange rate is often used as an instrument in economic management or as an economic policy. Exchange rate policy is regarded to be important when economic policies are aimed both at stabilizing the volume of transactions and at avoiding inflation. The changes in volume of transactions are resulted from the changes in competitiveness, which is defined as the relative prices of domestically produced commodities in the world market. The competitiveness is then seen as an intermediate target of exchange rate policy aimed to changes in the international transactions.

I.2. Conventional theoretical approaches

I.2.1. The Elasticity approach:

Trade balance[5] changes including exports changes and imports changes are influenced by the price elasticity of demand for exports and imports. The price elasticity of demand for exports is the percentage change in exports over the percentage change in price as represented by the percentage change in the exchange rate (foreign elasticity of demand for exports). The price elasticity of demand for imports is the percentage change in imports over the percentage change in their price as represented by the percentage change in the exchange rate (home currency elasticity of demand for imports).

A devaluation policy will be effective when the Marshall-Lerner condition holds, that is when the sum of the price elasticity of demand for exports and the price elasticity of demand for imports is greater than unity. If the sum of these two elasticities is less than unity, devaluation will lead to a deterioration of the trade balance.

I.2.2. The Keynesian approach:

Keynesian models of an open economy can be integrated with the elasticity approach to investigate the effectiveness of devaluation as a policy instrument. This means that with the demand determined output, devaluation will be expansionary as long as the Marshall-Lerner condition holds; it will increase net exports, aggregate output and employment. From the study of aggregate demand, we can see that the effects of the devaluation depend on both the Keynesian income multiplier and the demand elasticities for domestic exports and imports. The reason is that devaluation affects income by means of an expenditure-switching effect, shifting the expenditures of foreign and local residents toward domestic goods. As a consequence, the larger the demand elasticities for imports and exports, the stronger the impact of the devaluation on income.

I.2.3. The absorption approach:

The absorption approach was developed by Alexander (1952). In this approach, the trade balance surplus equals to the excess of income over domestic expenditure:

CA = X - M = Y - A

Where CA = X - M is the current account[6], Y is national income, A = C + I + G is the domestic absorption (expenditure), X is exports and M is imports.

The most important insight of this approach is the distinction of the two basic ways in which domestic policies can affect the current account. First, expenditure reducing requires expenditure to fall in relation to real income. Second, expenditure switching requires the composition of expenditure to move from foreign to domestic goods. In this case, if there are unutilized resources, the switching of expenditures will generate an increase in real income as a result of an increase in output, and thus in an improvement of the current account.

I.2.4. Dynamic model

Faik Koray (1990) focused on the relationship between trade balance and exchange rate in an equilibrium business cycle model. Two-country equilibrium model of the world economy analyzes the co-movements in the exchange rate and trade balance in response to exogenous disturbances: the confusion between monetary and supply shocks, and the confusion between shocks to permanent and transitory government purchases.

If there is a positive shock to domestic money supply, two effects will occur. The direct effect is the proportional exchange rate depreciation. The indirect effect is exchange rate appreciation with less than proportional level. However, the net effect is depreciation in exchange rate. Besides, the perceived shock does not lead to change in trade balance, but the misperceived shock will lead to increase in aggregate demand, increase in domestic production, then lead to deterioration of trade balance.

If there is a transitory shock to government expenditure, the indirect effect is appreciation of exchange rate and higher aggregate demand accompanied with decline in domestic production. In the end, trade balance deteriorates. In contrast, if there is permanent shock to government spending, exchange rate will appreciate but trade balance is intact.

In conclusion, Faik shows that policies directed at reducing trade balance deficits via a depreciation of the exchange rate either by Central Bank intervention or by excessive domestic money growth are counterproductive. Negative shocks to domestic transitory government purchases or positive shocks to foreign transitory government purchase which depreciate the exchange rate, on the other hand, improve the trade balance deficits.

Besides, the relationship between exchange rate and trade balance is also analysed by monetary approach and Dutch Disease. However, in these two cases, the impact is adverse, that is the exchange rate is influenced by the changes of trade balance, and trade balance in turn will change with the changes of competitiveness.

II- Empirical Evidences

II.1. Arguments in the impact of devaluation on trade balance

II.1.1. Structuralist’s point of view:

Structuralists argued that a devaluation could worsen rather than improve the balance of payment. Devaluation may work better for industrial countries than for less developed countries. Many LDCs are heavily dependent on imports of production inputs, so that their price elasticity of demand for imports was likely to be very low. While for industrial countries that had to face competitive exports markets, the price elasticity of demand for their exports may be quite high. So Marshall-Lerner does not hold for the case of LDCs.

The analysis of exchange rate policy become more complicated in this case as it affects at the same time aggregate domestic demand as well as supply. There are, in other words, aspects of supply-side, structural policy as well as demand side, absorptive effects, inherent in the use of this instrument. The Marshall-Lerner condition does not hold for the case of SSA. With regard to imports, demand elasticities tend to be low due to the heavy dependence on imported inputs, which must be paid for in scare foreign currency. In addition, even if exports demand is assumed to be rather elastic, many SSA countries produce goods for which the supply elasticity is not infinite due to the underlying structural characteristics of the economies. Thus, a devaluation may, particularly in the short run, cause results, which are unexpected from an orthodox perspective.

Concerning with the devaluation, some structuralist economists argued that short-, medium- and long-term effects must be distinguished, and that devaluation may lead to increases in unemployment and stagflation in the short run. The short-term impact of devaluation on output hinges on whether the negative effects on aggregate demand are outweighed by the positive impact on supply. This in turn depends on whether output is close to full capacity output or not, and on possible short-term supply constraints. Devaluation will at least in the short run tend to be inflationary, through the increase in imports costs, and this impact may be substantial in the very open imports dependent economies such as those of developing countries, for example sub-Saharan African countries.

II.1.2. A study of real effective exchange rate

From the study of Agnes Csermely (1993) in exchange rate policy in former socialist countries, it is clear that the impacts of exchange rate are often on both price level (inflation) and current account deficit. Almost former socialist countries suffered from current account deficit widening after an adjustment in exchange rate. In the study, he introduced a measure of real effective exchange rate (REER).

Through a study of Hungary in 1990-1992, with the question that how can competitiveness be improved, Agnes said that trade surplus may be achieved through the artificial dampening of the exchange rate, but not as a strategy for improving competitiveness if in the long run, there is no increase in living standard. The competitiveness of Hungarian production could be improved by devaluing of forint and by lowering the cost in terms of dollars and unit cost. It is obvious that a single devaluation may only be successful if it is supported by an economic policy restricting demand. Real devaluation is regarded as the most efficient method of bringing the economy into external equilibrium.

I.1.3. Case of J-curve

Empirical experiences of many countries show[7] that right after the devaluation time, the country faces deterioration in trade balance. After a longer time, the trade balance would improve. This situation is explained by the J-curve effect analysis. Over the short run, the value of these elasticities is rather small because both exports and imports are less responsive to changes in relative prices. However, over the longer periods of time, the volume of exports and imports would respond to relative price changes and the effects on the trade balance would tend to be positive, so that would lead to improvement in trade balance.

I.1.4. Other studies

In a study of how trade flows respond to relative prices, Carmen (1994) showed an examination about the relationship between relative prices and imports and exports in a sample of 12 developing countries[8].

In general, the countries in the sample appear to meet the static Marshall-Lerner condition for stability, as changes in relative prices do produce long-run reallocation of trade flows. However, the sign of the relation between the terms of trade and the trade balance will depend on the elasticity of substitution between the imported and home goods rather than in the fulfillment of the static Marshall-Lerner condition[9]. In these models what remains essential is that consumption responds to price changes, a condition for which we find ample empirical evidence.

In a conclusion, several empirical regularities emerge. First, the analysis suggests that income and relative prices are both necessary and sufficient to pin down steady-state trade flows. However, the traditional specification appears to fare better when modelling developing country demand for imports than when being applied to industrial-country demand for exports from developing countries. The latter may suggest that a fruitful area to investigate is intra-developing country trade. Second, it is found that, for the majority of cases, the relative prices are a significant determinant of the demand for imports and exports. Third, while relative prices have a predictable and systematic impact on trade, price elasticities tend to be low, in most cases are well below unity. Finally, while industrial-country income elasticities are well above those of their developing-country Asian and Latin American counterparts, this is not the case for Africa. The high primary commodity content of African exports probably accounts for this result.

II.3. Studies of Vietnamese economists

By considering the fluctuations of monthly exchange rate in 1993 compared to 1992, Vu Ngoc Nhung (1994) favored devaluation for promoting exports. The reason is that with the inflation of about 6-7 per cent and a devaluation by 8-9 per cent in December 1993, the loss of reduction of exports value is traded off by the cheaper imports price and reduction of imports value, and therefore trade surplus[10] was achieved. Also in the paper, he said that those authors opposing devaluation have mistakes in some problems. These problems are that the current exchange rate could promote Vietnam’s production. He concluded that in Vietnam devaluation is a good instrument for a better economic performance. However, in this case, export will be more expensive so that export value is not necessarily higher.

From the analysis of current situation of Vietnam's economy, Le Viet Duc and Tran Thi Thu Hang (1995) pointed out that the loss from devaluation is more than gains. At that time, it was not suitable to carry out a devaluation. Even though Vietnam suffered from serious deficits in current account and balance of payment, this is indispensable for a developing country being in the process of attracting foreign investment and foreign aids. This process is often accompanied by reduction of domestic interest rate, inflation and appreciation of domestic currency. But this is only the negative impact in the short run. In the medium and the long run, loans with low ICOR would be more efficient and profitable; therefore economic growth rate would increase. At the same time, this would automatically lead to real devaluation without any nominal devaluation, and so increase competitiveness.

Considering the deficits of trade balance and balance of payment, they showed that the low exports growth rate is not due to exchange rate changes. Data from 1988-1994 shows that devaluation is not accompanied with improving trade balance deficit. By a quantitative analysis checking Marshall-Lerner condition, the result is that the sum of elasticities of demand for imports and exports is much lower than unity. So that Marshall-Lerner does not hold for the case of Vietnam during 1988-1995.

Nguyen Thi Hien (1995) and Truong Xuan Le (1995) are among those opposing devaluation as a solution for improving trade balance. They considered that devaluation is not a unique solution for exports promotion.  In case of Vietnam, exports and imports are rather irresponsive to exchange rate, there are many other variables that have more effects on trade. In addition, the impact of devaluation is stronger and negative on many economic fields and variables like inflation, purchasing power of domestic currency...

Other experiences of devaluation are from the context of East Asian Crisis. The affected-countries’ economies turned down with the collapse of financial markets and banking system. Empirical evidences for the consequences of crisis are the reduction of economic growth to nearly zero in 1997 and the loss of confidence of local currencies, which can be seen from the below table.

The crisis left many serious consequences to the regional countries. The worst-affected countries are Thailand, Indonesia, Korea, and Malaysia. During the crisis, these countries were facing series of collapse in financial and monetary system, and then the loss of local currencies’ confidence. All these countries took devaluation in 1997. As a result, the changes in the GDP growth rates and trade activities are rather positive. In general, both exports and imports decrease sharply but balances of trade are improved.  However, there are other reasons for the changes in trade rather than devaluation. Firstly, lower GDP growths decreased domestic demands for imported goods. Secondly, crisis-affected economies need recovering by concentrating domestic resources on restructuring the economies. Both exports and imports reduce by about 30-40 per cent. The more reduced imports may be the reason for improving these countries’ competitiveness in dollar terms, so that increases exports and lowers imports to some extent. In general, devaluation is one of the factors leading to the improvements in trade balance of crisis-affected countries. It is still not agreed whether devaluation is an important factor.

Recently in Vietnam, there have still been debates of the impact of exchange rate on trade balance. An article in 1998[11] discussed about the improvement of trade balance by devaluation as the financial crisis happened in East Asia and devaluation were taken place in many regional countries. The article showed that a devaluation of VND brought good conditions to exports and reduced the country’s trade deficit. The decision to adjust the exchange rate in August 1998 improved competitiveness of Vietnam’s exports. The adjustment reduced the imports and improved the trade balance. According to the article, Vietnam’s trade deficit was expected to reach USD 1.91 billion as compared to the figure of USD 2.35 billion lower than 1997’s figure. The recent adjustment in exchange rate seems to have no pressure on inflation.

Pham Chi Quang (1999) showed a negative impact of devaluation on trade balance by checking Marshall-Lerner condition for the case of Vietnam. Using exchange rates recorded (including official exchange rate, buying exchange rate, and selling exchange rate in HoChiMinh city), he received a strict relationship between income and trade balance but not between exchange rate and trade balance. Therefore, he argued that devaluation could not be a unique instrument in improving trade balance. Other policy variables might seem to be much more efficient.

III- Approach for analyzing the case of Vietnam

For the case of Vietnam, the answer for whether devaluation improves trade balance is still in consideration. In this thesis, I’d like make an analysis in Vietnam's performance of trade and the impact of exchange rate on trade. In addition, I'd like to use the elasticities approach to check if exchange rate has a positive or negative relationship with trade. The approach to checking Marshall-Lerner condition is as follows:

TB = X (GDPf, E) - M(GDPd, E)

Where TB is the trade balance, X is exports, GDPf is the foreign income, M is imports, GDPd is the domestic income, E foreign exchange rate (NER, RER or REER) - E increase implying depreciation and E reduce implying appreciation.

The responsiveness of the demand for exports and imports to a devaluation is measured by the price elasticities of demand for exports and imports (for exports: hX, for imports: hM ), which measures the percentage change in exports or imports due to 1% change in the relative prices of foreign or domestic goods.

That is  hX = %DX / %DE     and             hM  =  - %DM / %DE

The Marshall-Lerner states that the direct effect of a devaluation on the trade balance will be positive (i.e. improvement in trade balance) when the sum of the price elasticities of demand for domestic exports and imports exceeds 1 (hX + hM > 1)[12].

Using the elasticities approach in combination with the examination of the structure of Vietnam’s imports and exports and the traditional exports and imports functions during 1989-1998, I hope that devaluation may bring about some positive results. By the way this could suggest the way to improve trade balance, and to reaffirm the government’s decision to devalue VND.

 


Chapter three: Vietnam's trade performance

and the exchange rate policy

I. Overview of Vietnam's economic reforms in 1989-1998 period

I.1. Review of the main reform policies and economic performance before and after 1989

The period of 1976-1979 was of unifying and turning the economy into an integrated whole in accordance with central planning principles. The state and collectives constituted the foundation of the economy from the production to distribution of factors and income, including foreign trade and foreign exchange management activities. Market and its forces did not have any function in the economy at that moment.

Changes in economic policies had been made from early 1980s. In agriculture, the contractual quota was widely applied in farming household in 1979 and early 1980s. In industry, the state authorized state owned enterprises to operate freely beyond the assignment of state plan. However, the state continued to maintain monopolistic power in controlling production and distribution by the two-price mechanism. In general, these changes in economic policies did not function in promoting the economic growth, stabilization and development.

The Sixth Party Congress in December 1986 marked the transition period in the Vietnam's economy. An overall transformation really took place with macroeconomic reforms. The multi-sectoral economy was recognized, the outward-oriented program replace the closed imports-substituting production. Structure of the economy changed in favor with light industries and services, especially goods and services for exports.

The culmination of the reform came in March 1989 with a series of radical changes which formally swept away most of the remains of the command economy and ushered in a new era of market economy. The main features of the economic reforms included tightened control over credit expansion, an increase in interest rate to positive level in real term, devaluation and unification of exchange rate and liberalizing all prices. These measures in banking and financial sectors pushed back the rampant inflation in the previous 1986-1988 period.

The 1989 reform programs were more comprehensive and thus made a watershed for the Vietnamese economy, as a fundamental transformation in economic management was begun. The results can be seen from the below macroeconomic indicators from 1989 up to now.

I.2. Trade reform

Vietnam had for years pursued an inward-looking development strategy, characterized by the orientation of agricultural and industrial activities toward the domestic market. Trading activities in the period before reforms were limited in trade agreements with the CMEA. Exports and imports were not promoted  but only implemented by SOEs. Price and volume of exports and imports were planned by government authorities.

With the introduction of “doi moi” in 1986, Vietnam started to take the process of economic structuring and creating institutional and policy environment for economic development. However, just in 1987, the changes affecting Vietnam’s interactions with international markets really started with the introduction of Law on Foreign Investment, the introduction of “open door” policy.

Since 1988, series of policies and regulations on trade, exchange rate and foreign investment were introduced to promote international activities. Firstly, the reforms were aimed at foreign exchange control, trading organizations and customs tariff. The Foreign Exchange Control Decree in 1988 liberalizes retention of foreign exchange, opening of foreign currency accounts, use of transfers to pay for imports and repay foreign loans: devaluation of exchange rates in trade and invisible payments. Also in 1988, the restriction on establishment of trading organizations relaxed and central government monopoly of foreign trade was terminated. Especially, trading activities became more active thanks to the Law on Imports and Exports Duties that introduces the custom tariff.

The changes in trade brought about by its actual factors become considerable from 1989. These factors included opportunities to participate in trade, tariffs, non-tariff barriers, foreign exchange control and exchange rate, and also international commitments.

In January 1989, the government decided to liberalize the establishment of foreign trade companies, resulting in the number of trading companies increasing from 80 in 1987 to 156 in June 1989[13]. Private companies were allowed to directly engage in international trade.

The reforms of tariff system were marked by the Law on Imports and Exports Duties 1988. Since 1993, Tariff Law was amended to add provisions for other than normal importation, the responsibility to initiate change in tariff was passed from Ministry to Ministry of Trade. In 1996, maximum tariff rate reduced to 80 per cent, special sales tax was imposed at rates up to 100 percent on imported passenger cars following the reduction in tariff rate.

In March 1989, exchange rate was devalued to a level that virtually unified it with the parallel market exchange rate. This devaluation replacing the early overvaluation implied an increase of the exchange rate for trade transactions within the plan from VND 900 per USD to 4500 per USD (end-of-period official exchange rate).

In 1991, foreign exchange trading floors were opened at the State Bank of Vietnam. The period after that saw another important reform that was the introduction of inter-bank foreign exchange market. At the same time, other regulations in foreign exchange transactions became more effective and closer to the world market's activities.

In addition, Vietnam's joining regional and multilateral trading arrangements has liberalized Vietnam's trade: signing a preferential trade agreement with the EU in 1992; joining ASEAN in 1995, it also became a member of the AFTA; in 1994, Vietnam was granted observer status at the GATT and in 1996 it submitted a memorandum on its foreign trade regime as part of its application for WTO. Also, Vietnam is currently negotiating a trade agreement with the United States. In November 1998, Vietnam became a full member of the Asia-Pacific Economic Cooperation (APEC) group, and submitted an Individual Action Plan (IAP) for meeting the liberalization objectives associated with membership.

In the "open-door" time, the increase of foreign investments has significantly contributed to the development of trade. The Law on Foreign Investment introduced in 1987 and its revisions in 1990, 1992 and again in 1996 has created a more favorable environment for foreign investment. Together with efforts such as the lifting of the US embargo, the changes have prompted substantial inward flows of foreign capital. And foreign investment has brought in its train a rapid expansion of imports of capital goods - and, more recently, producer goods - prompting requests for streamlining the trade regime and its administration.
