China's invasion and embellishment of rocky islands in the Hoang Sa and Truong Sa archipelagos under the sovereignty of the State of Vietnam into military bases and civil offices is a serious violation sovereignty of the State of Vietnam. This is also a violation of international law, the Charter of the United Nations, and the 1982 United Nations Convention on the Law of the Sea, eroding trust in international relations between the two countries, the region and the world. The State of Vietnam is the only country that has sufficient historical and legal evidence for asserting its sovereignty over the Hoang Sa and Truong Sa archipelagoes, when the Vietnamese State established sovereignty at least at the beginning of the year. In the seventeenth century, there was no established country and no objections. The State of Vietnam continues to fight to affirm its sovereignty over the Hoang Sa and Truong Sa archipelagoes, and at the same time requires the parties to return the rocky islands illegally occupied by Vietnam in the Hoang Sa and Truong Sa archipelagoes according to international law.
