The year of 1972 brought the marked aggravation of a series of political-economic conflicts in Brazil's relations with developing countries outside the Western Hemisphere, calling into serious question the continued viability of its efforts of several years to maintain good relations with both Portugal and the nonaligned states (particularly those of Africa). Following successful tours of Latin American countries in 1971, Foreign Minister Mário Gibson Barboza termed 1972 the “Year of Africa” and visited Zaire and eight countries of West Africa to advance Brazil's ambitions as a leader of the LDCs by offering technical assistance, development financing, and increased trade, cooperation in commodity agreements, and cultural exchange based on the African component of Brazilian culture. This tour was intended to promote the image of Brazil as a peacefully multiracial, rapidly developing tropical civilization eager to share with others the solutions to economic growth which it had found.
