The Conferences of American States, commonly referred to as the Pan-American Conferences, were meetings of the Pan-American Union, an international organization for cooperation on trade. James G. Blaine, a United States politician, Secretary of State and presidential contender, first proposed establishment of closer ties between the United States and its southern neighbors and proposed international conference. Blaine hoped that ties between the United States and its southern counterparts would open Latin American markets to US trade.
