At the international level, there are two important open access databases, developed by international organizations for policy makers and businesses: a list of agreements being negotiated. Agreements that have so far been discussed only in the absence of formal action by the parties concerned are not mentioned. Often, analyses of the free trade agreement show that its effects on both countries depend on the difference in value between the Canadian dollar and the U.S. dollar. In 1990-91, the Canadian dollar rose sharply against the U.S. dollar, making Canadian industrial products much more expensive to purchase U.S. products and making U.S. industrial products significantly cheaper for Canadians who no longer had to pay high tariffs on them. A free trade agreement (FTA) or treaty is a multinational agreement under international law to create a free trade area between cooperating states. Free trade agreements, a form of trade pacts, set tariffs and tariffs on imports and exports by countries, with the aim of reducing or removing barriers to trade and thereby promoting international trade.  These agreements „generally focus on a chapter with preferential tariff treatment,“ but they often contain „trade facilitation and regulatory clauses in areas such as investment, intellectual property, public procurement, technical standards, and health and plant health issues.“  A 2007 study showed that NAFTA had „a significant impact on the volume of international trade, but a modest impact on prices and well-being.“  List of agreements between two states, two blocs or one bloc and one state.
Free trade agreements, which are free trade zones, are generally outside the scope of the multilateral trading system. However, WTO members must inform the secretariat when new free trade agreements are concluded and, in principle, the texts of free trade agreements are reviewed by the Committee on Regional Trade Agreements.  Although a dispute in free trade areas is not the subject of litigation within the WTO`s dispute resolution body, „there is no assurance that WTO panels will comply and reject jurisdiction in a particular case.“  According to the Australian Department of Foreign Affairs and Trade, the trade imbalance between the United States and Australia increased significantly in 2007. The United States has become Australia`s largest source of imports, with more than AUD 31 billion in goods and services. However, Australia`s exports to the United States reached only $15.8 billion.  The real benefits of the agreement are not clear. Although President Donald Trump warned Canada on September 1 that he would exclude them from a new trade deal if Canada did not comply with its demands, it is not clear that the Trump administration has the power to do so without congressional approval. :34-6 According to reports by the Congressional Research Service (CRS), one was published in 2017 and another on July 26, 2018, it is likely that President Trump would need congressional approval for fundamental changes to NAFTA before the changes are implemented. :34-6 The year after the agreement, Australian exports to the United States were exported.
