To Challenge China in the South China Sea, Invite Taiwan to Participate in RIMPAC 2020. The Peoples Republic of China PRC seeks nothing less than complete control of the South China Sea, consistent with the infamous Nine-Dash Line. Dominance of the South China Sea offers China uncontested access to fisheries and hydrocarbons, control of international trade routes, domestic political benefits, and significant military advantages. Most importantly, it signalsChinas return to great power status. Inviting Taiwan to participate in RIMPAC 2020 is a provocative step that challenges norms and provides INDOPACOM with a course of action that can be modified to elicit the desired response. Through his action, the United States will demonstrate that it is prepared to contest the South China Sea, that it will develop partner capabilityinteroperability in the region, and that it is prepared for conflict with China should it arise.
