As soon as the agreements go beyond the regional level, they need help. The World Trade Organization intervenes at this stage. This international body contributes to the negotiation and implementation of global trade agreements. A free trade agreement is an agreement between two or more countries in which countries agree on certain obligations that affect trade in goods and services as well as the protection of investors and intellectual property rights. For the United States, the primary objective of trade agreements is to remove barriers to U.S. exports, protect U.S. interests abroad, and improve the rule of law in partner countries or countries of the free trade agreement. It is also important to note that a free trade agreement is a reciprocal agreement that is authorized by Article XXIV of the GATT. Autonomous trade agreements for developing and least developed countries are permitted by the 1979 decision by the signatories of the General Agreement on Tariffs and Trade (GATT) (“empowerment clause”) on differentiated and more favourable treatment, reciprocity and increased participation of developing countries. It forms the legal basis for the WTO`s Generalized Preference System (GSP).  Free trade agreements and preferential trade agreements (as mentioned by the WTO) are considered an exception to the MFN principle.  For example, a nation could allow free trade with another nation, with exceptions that prohibit the importation of certain drugs that are not authorized by its regulators, or unvaccinated animals or processed foods that do not meet their standards. The Doha Round would have been the world`s largest trade agreement if the United States and the EU had agreed on a reduction in their agricultural subsidies.
As a result of its failure, China has gained ground on the world`s economic front through cost-effective bilateral agreements with countries in Asia, Africa and Latin America. The interaction between trade rules and domestic policy, particularly regulation, means that trade negotiators face the difficult challenge of balancing reducing trade costs with maintaining appropriate space for optimal domestic regulation. The creation of free trade zones is seen as an exception to the most privileged principle of the World Trade Organization (WTO), since the preferences of the parties to the exclusive granting of a free trade area go beyond their accession obligations.  Although GATT Article XXIV authorizes WTO members to establish free trade zones or to conclude interim agreements necessary for their establishment, there are several conditions relating to free trade zones or interim agreements leading to the creation of free trade zones. Indeed, most of the countries affected by this national policy of the United Kingdom already have some form of free or preferential trade agreements with the European Union, in which the United Kingdom participates as an EU member state and which it benefits from. The UK government believes it will be able to negotiate more favourable bilateral trade agreements on its own than under a customs union and a single market of half a billion people. A fundamental principle for New Zealand is that any outcome in terms of services and investment must protect our government`s right to regulate for legitimate public policy purposes. Free trade agreements can facilitate visa access for New Zealand businessmen and our trading partners, which supports the development of our trade and economic relationships. Trade agreements are generally unilateral, bilateral or multilateral.
