JAKARTA, Indonesia — Indonesia is stepping up sea and aerial patrols of islands near the disputed South China Sea, an official said Saturday, following a diplomatic spat over “trespassing” Chinese vessels.
Military aircraft and three warships with some 600 navy, army, and air force personnel have been deployed to waters around the Natuna Islands, which border the South China Sea.
Indonesia has detained Chinese vessels in the fishing-rich waters in the past.
“Territorial violations by foreign vessels in Indonesian exclusive economic zone… is a threat to Indonesian sovereignty,” defense commander Vice Admiral Yudo Margono said in a statement.
The move comes after Indonesia summoned the Chinese ambassador this week and lodged a “strong protest” over a Chinese coast guard vessel escorting Chinese fishing boats around the islands in mid-December.
Beijing responded that it has “historic rights” in the region and that fishing boats had been carrying out “legal and reasonable” activities.
China lays claim to huge swathes of the South China Sea, where it is accused of building military installations and artificial islands — and ramming fishing vessels.
Vietnam, Taiwan, the Philippines, Malaysia, and Brunei also have claims in the South China Sea.
Beijing claims the majority of the resource-rich waterway through the so-called nine-dash line, a vague delineation based on maps from the 1940s as the then Republic of China snapped up islands from Japanese control.
Indonesia does not have a claim in the South China Sea but said it would not tolerate incursions by China — a key trading partner — into its nearby waters.
“There is no compromise on Indonesia’s sovereignty,” presidential spokesman Fajroel Rachman said Saturday.
