 After the War of Independence, the relations of Mexico were focused primarily on the United States, its northern neighbor, largest trading partner, and the most powerful actor in hemispheric and world affairs.Once the order was reestablished, its foreign policy was built under hemispheric prestige in subsequent decades.Demonstrating independence from the U.S., Mexico supported the Cuban government since its establishment in the early 1960s, the Sandinista revolution in Nicaragua during the late 1970s, and leftist revolutionary groups in El Salvador during the 1980s.
