In November 2020, fifteen countries signed the Regional Comprehensive Economic Partnership (RCEP), shaping a new free-trade zone in Asia and the Pacific by joining together some of the largest economies in the world such as South Korea, Japan, and China. Despite being geographically located in the middle of this trade-zone, Taiwan is excluded from this agreement. To understand how it perceives the exclusion and explores the concerns of the Taiwanese people, we have crawled comments from Sina Weibo in China and YouTube in Taiwan that contained the keyword "RECP." Semantic Network Analysis shows that Chinese mainlanders' netizen's comments mainly discuss the economic impact. In contrast, Taiwanese netizens seem to be primarily concerned about China.
