Exclusive economic zone of Indonesia

Parts of China's nine-dash line overlap Indonesia's exclusive economic zone near the Natuna islands.

Indonesia believes China's claim over parts of the Natuna islands has no legal basis.

In November 2015, Indonesia's security chief Luhut Panjaitan said Indonesia could take China before an international court if Beijing's claim to the majority of the South China Sea and part of Indonesian territory is not resolved through dialogue.

[6] On 26 May 2020, Indonesia sent a formal letter to the United Nations which said "Indonesia reiterates that the Nine-Dash line map implying historic rights claim clearly lacks international legal basis and is tantamount to upsetting UNCLOS 1982," “As a State Party to UNCLOS 1982, Indonesia has consistently called for the full compliance toward international law, including UNCLOS 1982.

Indonesia hereby declares that it is not bound by any claims made in contravention to international law, including UNCLOS 1982,"[7]
