Brazilian President Dilma Rousseff and Chinese Premier Wen Jiabao have just signed a number of new trade agreements, that they hope will boast both economies. Jiabao, who is in Brazil to attend the U.N. Rio+20 sustainable development summit, met with Rousseff to hammer out agreements for mining, industrial, aviation and infrastructure areas. They want to encourage more commerce flow between the two countries.

As Brazilian Finance Minister Guido Mantega said “The relation with China is greatly relevant for us because it is our most important trading partner. In spite of a potential slowdown, China will keep being the place where to do business, a dynamic economy.”

China and Brazil have had to overcome a number of economic conflicts to reach the agreements they have now created.  Since Rousseff came to office in 2011, Brazil has complained that they have manufacturing roadblocks in China. They have blamed China with flooding the Brazilian market, as well, with cheap imports that hinder the growth of local factories.

China has also complained that Brazil has raised taxes on Chinese-made cars and has created barriers on products that come from their country.
