Manley expressed support for African liberation in countries such as Angola, which successfully fought off the apartheid armies of South Africa with Cuban help. However, the USA labelled Jamaican support for African liberation as "hostile", and the US government was critical of the Manley government for their close relationship with Fidel Castro's Cuba. When Henry Kissinger visited Jamaica in 1975, he warned Manley against supporting Angola and Cuba. When Manley turned down Kissinger, the US allegedly increased its supply of weapons to supporters of the JLP, resulting in a sharp upturn in political violence. More broadly there was a deterioration of relations between the United States and Jamaica during Manley's tenure beginning with the Nixon administration and continuing on with the Ford Administration due to allegations of CIA activities on the island. Attempts at an improvement of relations were made during the Carter Administration.
