Abstract: This paper is concerned with the issues of China-Brazil cooperation on the issues under study and the impact of China's energy policy on these relations in the XXI century. In his work the author highlights that cooperation in this area in the early 2000s was extremely limited but in 2007 Brazil became one of the largest South American oil suppliers to China. China is also interested in Brazil in terms of biofuels, as this Latin American state is one of the leading producers and exporters of this type of fuel. The author considers the increasing importance of renewable energy sources for the energy policy and security of the PRC. The author believes that the China-Brazil energy relations were influenced by BRICS which created the necessary cooperative environment for collaboration. The article analyzed the statements that were made at the nine BRICS summits (2009-2017). The methodological basis of the article is scientific methods based on the requirements of an objective and comprehensive factor analysis of the China-Brazil energy relations. The research was carried out with the help of a set of methods and means of scientific knowledge. The author comes to the conclusion that strengthening of cooperation in the energy sector between China and Brazil is caused by a rapid economic growth of China which requires the development of the energy industry. Brazil, in turn, is interested in Chinese investment and technology. The author concludes that the potential for cooperation between the two countries is enormous and that the governments will increase the level of cooperation in the researched field.
