近年來巴西和中國他們的貿易量大幅增加。由於貿易量的增加，同時會使其他層面的交易量提升，例如在軍事方面。由此可知,即使他們在貿易時觸礁,他們之間一次又一次的成功解決這些問題。有可能是因為他們必須抑賴彼此,所以得設法解決雙方的問題,特別是在巴西這一方。由於中國和巴西的關係日趨友好,所以美國也希望和南美洲地區發展友好關係。 Brazil and China have, in recent years, greatly increased their trade relation with each other. This in turn could possibly lead to other aspects of their relations to increase such as miltary aspects. We can see that eventhough thier relations have at times been on the rocks, they have time and time again solved those issues. The reason for their continuous relation can be due to their increase dependencies on trade with each other, especially in Brazil''s case. This increase in relations between China and Brazil has also lead to an increase in US interest within the South American region.
