Since the establishment of Forum for Economic and Trade Co-operation betweeen China and Portuguese-speaking Countries (Macao) in 2003, there has been a rapid growth of trade between China and Portuguese-speaking countries. It is essential to study the trade competitiveness and complementarity of different industries for the trade promotion. Based on the SITC classification trade data from 2003 to 2015 and using export RCA, ESI and TCI indices, we analyze the export comparative advantage, export similarity and trade complementarity respectively. It is found that the export comparative advantage between China and Portuguesespeaking countries is rather complementary than competitive.
