Given that European regionalisation has been able to launch many other regional trade agreements in Africa, the Caribbean, Central and South America, it has also helped to advance the GATT agenda, with other countries seeking further tariff reductions to compete with the preferential trade that the European partnership has produced. Thus, regionalism has not necessarily increased at the expense of multilateralism, but in conjunction with it. The advance towards regionalism was probably due to the growing needs of countries to go beyond the GATT provisions at a much faster rate. Compared to the total GDP of its members, the trading bloc is the largest in the world since 2010. NAFTA has two complements: the North American Environmental Cooperation Agreement (NAAEC) and the North American Worker Cooperation Agreement (NAALC). The goal of NAFTA was to remove trade and investment barriers between the United States, Canada and Mexico. As far as the United States is concerned, the country has never participated in the trade liberalization that swept Europe in the first half of the 19th century. But in the second half of the century, protectionism grew considerably with the increase in tariffs during the Civil War, and then the mcKinley ultra-protectionist tariff law of 1890. While policy-making and most aspects of maricultural practice were seen as purely national concerns, they are becoming increasingly important internationally. As a result, States, while so far taking into account only national priorities in the definition of maricultural policy, particularly legislation/standards, will need such activities in the future to take into account international needs, including various bilateral and multilateral trade policies.

Examples of this trend include international standards for the public health of aquaculture products and the harmonization of trade controls. While the GATT aimed to promote tariff reduction between Member States and thus lay the groundwork for multilateral trade expansion, waves of regional trade agreements intensified over the next period.
