the geisel administration (1974–79) marked a definite cooling of brazilian–american relations. as the united states began to apply high tariffs on brazilian manufactured goods, ernesto geisel looked for new trade partners. these, he would seek mostly in other third world nations (in africa, for instance). but in contrast with costa e silva and médici, geisel commenced to reach out to communist countries, too. in 1975, four years before the u.s., brazil reestablished diplomatic ties with china. it promptly recognized the independence of fellow portuguese-speaking angola and mozambique, two african countries whose independence from portuguese rule had been brought about by socialist revolutions aided by cuba and the soviet union. in 1975, brazil voted in favour of resolution 3379, a u.n. resolution sponsored by muslim nations which equaled zionism with racism. only two other latin american countries—cuba and mexico—had voted in favour of the bill. in supporting it at the expense of israel, already then a major u.s. ally, brazil's intention was to seek closer relations with oil-rich arab nations. by then brazil imported 80% of the oil it consumed. as such it had been greatly affected by the 1973 oil crisis, an event which had a tremendously negative impact on brazil's current account and posed a major threat against its fast growth during the médici years.
