China
Ties between China and America are exceedingly complex, having seen tremendous highs and lows throughout history. Both countries perceive one another as a potential adversary but continue to maintain a strong economic partnership. China has essentially split down the middle in terms of how it views America, having plateaued at 49% approval for several years.
Brazil
Relations between Brazil and the U.S. have a long history. America was the first country to recognize Brazilian independence. Although the two countries have never been openly hostile toward one another, relations have been distant and occasionally tense. According to a global poll, only 65% of Brazilians view the U.S. favorably.
