‘Watch yourself’: Beijing warns South Korea after remarks on South China Sea clashes

China had “always made timely representations and stated opposition” to South Korea’s criticism, he said.

“I once again urge South Korea to watch yourself, refrain from following the trend of hyping the issue, and avoid adding unnecessary burdens on China-South Korea relations.”

Lim Soo-suk, a spokesman for South Korea’s foreign ministry, said last Thursday that Seoul was “deeply concerned about the dangerous situation” and “use of water cannons against the Philippine vessels in the South China Sea”.

“We support the maintenance of peace, stability and a rules-based order in the South China Sea, as well as the freedom of navigation and overflight based on the principles of international law, including the United Nations Convention on the Law of the Sea,” Lim said.

South Korea’s embassy in Manila also voiced concerns on its social media account.

The remarks came after yet another clash between China and the Philippines last Tuesday near the Second Thomas Shoal, a recurring flashpoint between the two sides over the last year.

Manila says Beijing’s South China Sea proposals go against national interests

The Philippine coastguard accused a Chinese vessel of ramming and damaging one of its ships, and injuring four Filipino crew members with water cannons.

The Philippine ships had been sent to resupply military personnel stationed on a wrecked ship that was intentionally scuttled on the reef in 1999. Chinese ships have continuously blocked the resupply efforts, resulting in frequent confrontations.

Wang defended the Chinese intervention, saying the incident was caused by “the violation of China’s territorial sovereignty and maritime rights and interests by the Philippines”.

“The Chinese side took the necessary control measures in accordance with the law and operated professionally with restraint, reasonably and legitimately. The responsibility for the incident lies entirely with the Philippine side,” he said.

The Second Thomas Shoal, known as Renai Jiao in China and Ayungin Shoal in the Philippines, is an uninhabited reef located within the 200-nautical mile exclusive economic zone of the Philippines. China claims sovereignty over the reef as well as the entire Spratly Islands, through a loosely defined “nine-dash line”.
