relations again cooled slightly after president jânio quadros took office. he ruled for only some months in 1961. quadros was an out-and-out conservative, and his campaign had received support from udn, brazil's then-largest right-wing party which, five years later, would morph into arena, the military dictatorship party. but quadros's foreign policy—named "independent foreign policy"—quickly eroded his conservative support. in an attempt to forge new trade partnerships, the brazilian president tried to create closer ties with some communist countries. that included cuba. quadros openly supported fidel castro during the u.s.-led bay of pigs invasion. he visited the caribbean nation after the event, and when cuban revolutionary ernesto "che" guevara retributed the visit, he was decorated with brazil's highest honor. as a result of the political instability within the country—something provoked by his breakup with the udn and tensions with the military—quadros resigned. at that time, his vice-president, joão goulart, was on a diplomatic mission in communist china.
