Is the Xisha Islands completely under the control of the People's Liberation Army and occupied by other countries? Especially Vietnam, thank you! !

Xisha Islands covers an area of about 10 square kilometer, and there are more than 40 Oko islands and reefs, mainly concentrated in two circular reefs of Xuande Islands and Yongle Islands. Among them, Yongle Islands include six island reefs such as Treasure Island and Ganquan Island, and Xuande Islands include Yongxing Island, Shidao Island and Qilianyu. All the islands are under the control of China. 1In August, 1977, the Chinese and Vietnamese governments held talks on the boundary and the demarcation of the Beibu Gulf. Ignoring historical facts and past commitments, Viet Nam openly claimed territory from China in an attempt to annex some islands belonging to Nansha and Xisha in China. China's unreasonable demands were resolutely rejected and condemned by the Vietnamese government, and China began to strengthen security in Nansha and Xisha Islands.
