Q: Recently Vietnam criticized China for erecting some sovereignty markers at some basepoints of territorial waters in Xisha Islands, accusing it of "violating the sovereignty of Vietnam and therefore being completely invalid. " What comment does China have?

A: China has indisputable sovereignty over Xisha Islands, Nansha Islands and adjacent waters, for which China has sufficient historical and legal grounds. Based on 1982 UN Convention on the Law of Sea and 1992 Law of the People's Republic of China on the Territorial Sea and the Contiguous Zone, the Chinese Government publicized basepoints of territorial sea in Xisha Islands. It completely falls within China's sovereignty to erect sovereignty markers on the basepoints of territorial sea in Xisha Islands, in which no country has right to interfere.
