evidence: The Natuna Regency, also known as the Natuna Islands, is a collection of about 154 islands in Indonesia’s Riau Islands province, 27 of which are inhabited. The islands fall between the Malaysian Peninsula to the west and Borneo to the east. [...] The Natuna Islands are at the forefront of territorial disputes between Indonesia and China – a factor that greatly increases the political risks of investing in the region. Indonesia claims the Natuna Islands as falling within its 200 nautical miles exclusive economic zone (EEZ), while China claims the islands under its "nine-dash line" historic rights claim. [...] Territorial disputes surrounding the Natuna Islands do not just occur in political statements. Chinese, Thai, and Vietnamese vessels have been known to fish in the area, in addition to Indonesian ones, which risks provoking a conflict. In 2016, Indonesian law enforcement seized a Chinese vessel accused of fishing illegally in Indonesian territory, but the Indonesian authorities were unable to return the vessel to the Natuna Islands because of interference from the Chinese coast guard.
