Regional Trade Agreements (RTAs) are the agreements whereby members accord preferential treatment to one another in respect to trade barriers. During the second half of the 1990's, trade liberalization and the pursuit of global free trade underwent a metamorphosis. The political momentum shifted away from what was seen by some nations as the painstakingly slow process of multilateral tariff negotiations to smaller regional and bilateral arrangements - the Regional Trade Agreement. RTAs are not a new means of trade liberalization; historically, whenever multilateral trade negotiations broke down, bilateral and multilateral free trade agreements filled the void. Such strategic trade arrangements have enabled many states to move towards freer trade at their own pace, and for their own benefits. For the overall country Thailand The more important it is to promote, organize, or allocate resources of the participating countries are party to the group, with operations being efficient (if it can be expanded very broadly refers to the efficiency in the allocation of resources in the world), but on the condition that the talks focus on. Multilateral trade mechanical duplicate (Multilateral Trade Negotiations) under the World Trade Organization (WTO) in the past, it is going slowly, and the current round of negotiations, it has occurred. From there, it's difficult for many to make many an ear, leading to a consensus (Consensus) reasons to make RTA/FTA is the way out, including alternative is one that many countries have carried out and are carried out continuously to the EU, such as AFTA NAFTA, etc. However, the basis of which Thailand is a party such as the RTA AFTA still going relatively slow due to the performance of each country is different. In addition, the economic superpowers, especially the United States (a major trading partner of Thailand) is trying to accelerate the FTA with other oils made several important trading partners of the country, and some countries have also made Thailand FTA with other countries, so. If the operation is delayed in Thailand to make the FTA may make a market in Thailand's export expansion and not contraction. That has resulted in the economic structure within the country, not to change the adjustment of the external world, focusing on strengthening the competitiveness of the country in accordance with the existing and potential that must be recreated to sustainable growth. After the establishment of this group, of course, is that it's up to the great benefit in the preparation of a free trade area. If carried out according to the rules and etiquette, the benefit is truly a consumer to consume the product and receive a quality service at a lower price than prior to the liberalization of goods and services, it also offers a more variety. While the manufacturer or entrepreneurs who protected or have handicap from the official, no matter be. Subsidies to set up a rival drum import goods produced in the country. Or with other methods and measures it will compete against products imported. And if these operators do not adapt tore eventually. Therefore, the process of free trade is to help member countries and must occur according to the globalization. That led to the modification of the domestic economic structure as a whole to strengthen the country's strength, based on the potential use of market mechanisms, guidance on economic activity, including guidance eliminates the restrictions or obstacles to economic activity and enables trade and investment from abroad.
