The article examines the impact of free trade agreements between ASEAN and five other countries on trade creation and diversion. The researchers used a trade gravity model with dummy variables and static panel data regression to analyze the effects of these FTAs on intra-regional trade flows. The results show that only ACFTA and AIFTA had a trade creation effect, while other FTAs led to trade diversion, harming member countries. This suggests that more evaluation and efforts are needed to make FTAs beneficial for all involved.
