The fifth advantage applies to emerging markets. Bilateral trade agreements tend to favour the country with the best economy. This puts the weaker nation at a disadvantage. But strengthening emerging markets helps the developed economy over time. Environmental impact assessment (EIA) can also be an important legal instrument that is increasingly applied to mariculture. The timely application of EIA (which covers social, economic and environmental issues) to large coastal crop projects can be a means of correctly identifying environmental problems at an early stage of projects, thus integrating appropriate environmental management measures into project design and management. Such measures will ultimately make the project more sustainable. A major difficulty with EIA is that it is difficult (and generally impractical) to apply to small-scale mariculture developments, which are common in many parts of Asia, and do not easily take into account the potential cumulative impact of many small farms. Strategic environmental assessment (SEA) can provide a broader way to assess impacts.
A large number of problems can be illustrated by the number of countries that are members of the WTO, i.e. 149 out of less than 30 when GATT was created in 1948. Tariff reductions under GATT have taken place in a series of trade cycles, the last of which was linked to the Uruguay Round (1986-94). The fact that trade cycles have been controversial, long and often difficult, and that they have not led to the removal of barriers to trade in agriculture or the services sector, has led to the belief that trade negotiations could be more effective if applied to a smaller number of countries. In turn, the global trading system could be managed more effectively within the framework of a system of regional blocs in which the objectives of trade liberalization are more modest, so that the overall result is that of mini-Latinism than multilateralism. Multilateral trade agreements are concluded between two or more countries in order to strengthen the economies of member countries through the exchange of goods and services between them. The multilateral trade agreement strengthens trade relations, trade facilitation and financial investment between the member countries of such a multilateral trade agreement. .
