Recently, the "Hailian Reception Hall-Brazil and BRICS New Industrial Revolution Partnership Innovation Base Promotion Conference" was held in S?o Paulo, Brazil, where 8 Xiamen enterprises signed 8 projects on the spot, to carry out more extensive and in-depth cooperation with Brazilian parties in the fields of intelligent manufacturing, biotechnology, and new energy, with a signed amount exceeding 1 billion US dollars. This is also the first time the Hailian Reception Hall Of Xiamen Municipal Bureau Of Commerce has been held overseas. The event helped enterprises "go out" and "bring in" investment, promoting Xiamen's business environment and the BRICS PartNIR Innovation Center, attracting foreign businessmen to pay attention to Xiamen and invest in Xiamen, and paving the way for Xiamen enterprises to expand their Brazilian "circle of friends" and open up international markets. The signing of 8 high-quality projects is a vivid portrayal of the good economic and trade relations between Xiamen and Brazil. In 2022, the total import and export volume between Xiamen and BRICS countries reached 13.6 billion US dollars, with a growth rate of 29.9%. Among them, the trade volume with Brazil was 3.99 billion US dollars, accounting for the largest proportion.
