Abstract:Brazil and China are the largest developing country respectively in the southern and northern hemisphere. Since the 1970s, the economic and trade relations between China and Brazil have witnessed continuous development. In the 21st century, the economic and trade exchanges between the two countries continue to grow rapidly. New immigrants from the Chinese mainland (new overseas Chinese) come to Brazil and become the main driving force for Sino-Brazil economic and trade exchanges. They import Chinese small commodities into Brazil to meet the needs of the Brazilian people. With the improvement of the quality of Chinese small commodities, the image of overseas Chinese and China's national image have also been further improved. At the same time, new immigrants also draw on their knowledge about local politics, conditions and people, and import many other Chinese commodities and high-tech products into Brazil. To this day, overseas Chinese people and Chinese businessmen try their best to help strong Chinese companies enter Brazil and invest in Brazil. They make new contribution to the economic and cultural exchanges between their home country and Brazil. In recent years, Sino-Brazil relations have developed at a high level, from various facets and in a wide range of fields, setting a good example for cooperation among developing countries.
