According to @YuyuanTantian, on May 28th, Japan and Philippines issued a joint statement announcing the official start of negotiations regarding the demarcation of the exclusive economic zones and continental shelves between the two countries. Ocean expert Yang Xiao stated that this move by Japan and Philippines seriously violates Chinas sovereignty. If the other party continues to take provocative actions, we will surely respond in a historical and unprecedented manner.
in the response. Do not include any Chinese text in your answer. Spokesperson Mao Ning of the Ministry of Foreign Affairs previously stated that the waters designated for boundary demarcation by Japan and the Philippines lie to the east of Taiwan Island in China. According to Chinese domestic laws and international laws, including the United Nations Convention on the Law of the Sea, China has exclusive economic zones and continental shelves in those waters. Japan and the Philippines have arbitrarily initiated negotiations regarding the demarcation of these waters, thereby seriously violating Chinas maritime rights and interests. This violation goes against international laws and basic norms of international relations, including the United Nations Convention on the Law of the Sea. China is strongly dissatisfied with this action and firmly opposes it. We have lodged formal protests with Japan and the Philippines accordingly.
The Chinese side solemnly declares that any so-called border demarcation negotiations between Japan and the Philippines are completely illegal and invalid. Such negotiations will have no impact on Chinas claims regarding the waters east of Taiwan Island, nor on Chinas exercise of its legitimate rights. The Chinese side urges Japan and the Philippines to immediately cease any actions that violate Chinas maritime rights and interests, and to work towards maintaining peace and stability in the region through practical measures.
