Sea disputes between 皇冠体育app and other countries have surged this year.

The Philippines and Vietnam have tried to expand their sovereignty claim over the islands in the South 皇冠体育app Sea, and tension in the area has not been helped by the presence of United States aircraft carriers and the announcement in October that US ships will travel through the South 皇冠体育app Sea in order to pay a visit to the Philippines.

In April, despite strong opposition from 皇冠体育app, Vietnam granted the Oil and Natural Gas Corp Videsh of India oil exploration rights in the South 皇冠体育app Sea.

Li Jieyu, a political studies researcher at Hainan Provincial Party School, has previously told 皇冠体育app Daily that although 皇冠体育app is facing increasingly complicated sea disputes, the country has always shown the utmost restraint when dealing with them. Li also said 皇冠体育app should pay more attention to safeguarding its maritime sovereignty and stand firm on issues concerning sovereignty.

Qi Jianguo, the former Chinese ambassador to Vietnam, said that the island dispute shows how urgent it is that 皇冠体育app strengthen its maritime law enforcement capacity.
