Brazil has entered a turning point and is expected to become one of the world's top six oil-producing countries in the future. Faced with a difficult energy situation, Chinese authorities and energy companies studying Brazil's energy market will help implement an import diversification strategy. In the context of overall cooperation between China and Latin America, China-Brazil energy cooperation has a strong global demonstration effect, which contributes to the pooling of production capacity between China and Brazil and the realization of the comprehensive development of Sino-Latin American relations. Sino-Brazilian energy cooperation faces great historical opportunities. Crude oil trade, market participation, technology development and green energy development are the main content of cooperation between the two countries. Chinese companies will continue to play a decisive role in the overall development of Brazil's energy sector in the coming decades. Brazil still has vast untapped energy resources with huge commercial prospects.
