evidence: The Natuna sea is within 200 nautical miles (370 kilometres) of Indonesia’s coastline, making it part of Indonesia’s Exclusive Economic Zone (EEZ). Since December 19, 2019, Chinese fishing vessels have trespassed into the waters around the Natuna Islands, violating Indonesia’s sovereignty as regulated by the 1982’s United Nations Convention on the Law of the Sea. [...] This is not the first time China entered Indonesia’s territory around the Natuna Islands. Back in 2016, Indonesia also had to ratchet up defence around the islands after an incursion of Chinese fishing armada and coast guard vessels into its EEZ.
