Indonesia's swift securitization of the Natuna Islands how Jakarta countered China's claims in the South China Sea

After being a neutral actor for decades in the complex South China Sea (SCS) territorial disputes, Indonesia has seen itself compelled by China's assertiveness to become firmer about protecting its territorial sovereignty around the Natuna Islands (NI). Jakarta is alarmed by China's claims that it has undeniable historical fishing rights in the NI territorial waters because they undermine Indonesia's territorial sovereignty. Our analysis loosely adopts the securitization conceptual framework proposed by the Copenhagen School to reveal that Jakarta swiftly securitized the NI issue between 2014 and 2016. Using a combination of quantitative and qualitative methods, this paper unpacks how the Indonesian printed mainstream media discussed the NI in recent years. By the end of 2016, the Indonesian media portrayed China's claims that it has historical fishing rights in the NI territorial waters as the most urgent national security threat to Indonesia, i.e. the NI issue was securitized. This analysis shows that the Indonesian people accepted Jakarta's security discourse, i.e. Jakarta had successfully securitized China's claims over the NI territorial waters. This paper makes a new contribution to the securitization literature by simultaneously analysing the Indonesian news and social media outlets.
