The 23rd China-ASEAN Expo will take place in Nanning, capital of southern China's Guangxi Zhuang autonomous region, from Sept. 17 to 21, the Ministry of Commerce announced Tuesday. This year's expo will build on a record bilateral trade of US$1.05 trillion in 2025, when China remained ASEAN's top trading partner for the 17th year and ASEAN remained China's for the sixth.
