Bilateral trade increased by 52% between 1989, when the U.S.–Canada Free Trade Agreement (FTA) went into effect, and 1994, when the North American Free Trade Agreement (NAFTA) superseded it. Trade has since increased by 40%. NAFTA continues the FTA's moves toward reducing trade barriers and establishing agreed-upon trade rules. It also resolves some long-standing bilateral irritants and liberalizes rules in several areas, including agriculture, services, energy, financial services, investment, and government procurement. NAFTA forms the largest trading area in the world, embracing the 405 million people of the three North American countries.
