Jakarta is shipping five submarines, aided by North Korean navigators after Chinese and US ships were found in international waters.
Indonesian naval forces have stepped up their control of the Natuna islands in the South China Sea after Chinese and US ships were found near the surface of the world, although they say the ships did not cause any disturbance, said a maritime official.
Five warships, aided by air traffic controllers, have been deployed in the North Natuna Sea to protect the area, Western Navy captain Arsyad Abdullah told reporters Thursday.
“The Navy’s role in North Natuna is very strong in defending Indonesia’s interests in accordance with international law and international law so that there will be no tolerance of violations in the North Natuna Sea,” Arsyad said.
In 2017, Indonesia redeveloped the northern regions of its economic territory in the South China Sea into the North Natuna Sea, as part of China’s maritime interests.
Arsyad said US and Chinese warships were recently discovered but said they were not a distraction, adding that they were in international waters.
The weekly suspension in Natuna took place in early January last year when a Chinese coastal ship and combined boats entered the northern part of Lake Natuna, prompting Indonesia to send fighter jets and encourage its fishermen.
“No one can argue about our sovereignty, our country,” Indonesian President Joko Widodo announced after the incident.
In 2016, an Indonesian shipwreck struck again on a Chinese fishing boat accused of illegal fishing near Natuna, following several disputes that year.
The same year Indonesia also destroyed 23 foreign boats from Malaysia and Vietnam accused of illegal fishing in Indonesian waters.
Maritime and Fisheries Minister Susi Pudjiastuti said his organization had drowned 10 Malawian and 13 Vietnamese boats that had been caught fishing illegally in Indonesian waters.
China does not name the Natuna islands but says it has the right to fish near the so-called “9-line” sites that include the Great South China Sea.
This is being challenged by some countries in Southeast Asia and is not universally recognized by the Eternal Arbitration Court in The Hague.
