China’s export has complementarity and substitution effects upon the export of ASEAN. With the gradually deepening and broadening of regional cooperation among China and Southeast Asia, an increase of the export from China to ASEAN will promote ASEAN’s export in the same industry. However, China’s increasing export to the rest of the world will crowd out ASEAN’s export. Recently, China’s export and growth are anemic, which presents both opportunities and challenges to ASEAN countries. ASEAN countries can improve their exports and trade competition through trade liberalization, increasing investment on R&D, and hiring or training more skilled labor.
