China patrols waters east of Taiwan in response to Japan, Philippine maritime border talks

BEIJING/TAIPEI, June 1 (Reuters) - China's Coast Guard on Monday said it had conducted "law enforcement" patrols in waters east of Taiwan in response to Japan and the Philippines' plans to ‌launch maritime border delimitation talks, which overlap with areas claimed by China.

Japan and the Philippines ‌said last week they would begin formal talks on delimiting the maritime boundary of the exclusive economic zone and the continental shelf ​between the two countries "in accordance with international law."

Delimitation involves the legal and cartographic process of defining a boundary between two regions or countries.

While they did not give details, China's foreign ministry on Friday said that area covered waters east of Taiwan, which Beijing views as its own territory, adding that such talks are "completely illegal, ‌null and void."

In a statement, China's ⁠Coast Guard said a flotilla had carried out the patrol in accordance with the law to the east of Taiwan, though it did not specify where exactly.

"This ⁠is a necessary action taken in response to Japan and the Philippines unilaterally announcing the initiation of maritime boundary delimitation negotiations in the waters east of China's Taiwan island," it said.

"We urge Japan and the Philippines to immediately ​cease ​all illegal actions that infringe upon China's sovereign rights ​and interests."

Taiwan's Coast Guard had no immediate comment. ‌The Philippine and Japanese embassies in Beijing did not immediately respond to requests for comment.
