Prisoner's Dilemma in the Rationalization of Indonesia's Foreign Policy in the South China Sea Dispute

China's nine-dash line claim in the South China Sea has posed a threat and instability in the regional area, including the waters of North Natuna. Indonesia's consistent foreign policy of remaining a neutral country changed under President Prabowo's leadership with the formation of a joint statement. The aim of this paper is to analyze which policy provides the greatest benefit to Indonesia using the Prisoner's Dilemma. The research method used is qualitative, with secondary data sources and descriptive analysis techniques. The conclusion shows that Indonesia’s highest score in interactions with China related to the South China Sea dispute is achieved by not cooperating, regardless of China's choices.
