[Ministry of Foreign Affairs: China’s construction and other activities on its own territory are legitimate and legitimate matters within the scope of sovereignty] On September 15, Foreign Ministry spokesperson Guo Jiakun hosted a regular press conference and stated that the Nansha Islands, including Mischief Reef, Subi Reef, and Thitu Island, are China’s inherent territory. China's construction and other activities on its own territory are matters within the scope of sovereignty and are legitimate and legal. The territorial scope of the Philippines is clearly defined by a series of international treaties, and the Nansha Islands have never been within the territorial scope of the Philippines. According to the principle of international law that "the land rules the sea," it is illegal for the Philippines to claim so-called maritime jurisdiction over Chinese territory. (CCTV News)
