The success of Economic and Trade Cooperation Forum between China and Portuguese-speaking Countries which was held in Macau indicates that Macao has started to become an international commercial trading platform with languages as a medium, which has great prospects for development. There are only less than 10 countries using Portuguese in the world, while there are more than 70 countries and regions using the Latin languages such as Spanish and French which are similar to Portuguese. China's relations with these Latin-speaking countries are relatively weak, and urgently demand to be expanded and deepened. Macao is the only region where China and Latin languages-speaking countries have traditional economic and cultural ties and a good foundation of the commercial trading platform between China and Portuguese-speaking Countries, so Macao can be upgraded to an economic trading platform between China and Latin-speaking countries so as to fully expand the friendly exchanges between China and various South European, Latin American and African countries, effectively guide the diversified development of Macao's economy and greatly enhance the international competitiveness, cultural soft power and global influence of China.
