The US policy on regional agreements changed in the later 1980s. It began in 1986 to negotiate a free trade agreement with Canada. Negotiations then began between the USA, Canada, and Mexico, leading to the establishment in 1994 of the NAFTA. This is broader in scope than most such agreement. Agriculture is covered, and the treaty was accompanied by supplementary agreements on labour and the envonronment, although there are no supranational elements. A first 'Summit of the America' was held in Miami in 1994, with the aim of achieving a FTAA as well as deepending cooperation in drugs, corruption, terrorism, hemispheric security, sustainable development, and the environment. By the first summit in Argentina in 2005, however, the political context of Inter-Americanism had significantly changed.
