Senior Colonel Ren Xiaofeng, director of the Maritime Safety Policy Research Office of the China Navy, said that China ships may not necessarily abide by the newly adopted Rules for Accidental Encounters at Sea (CUES) after encountering foreign ships in the disputed waters of the East China Sea (China's East China Sea) and the South China Sea (China's South China Sea). 2 1 member countries, including China, the United States and Japan, participated in the Western Pacific Naval Seminar held in Qingdao. At the meeting, CUES was adopted, which stipulated the mobile intelligence and communication procedures when naval vessels and planes met unexpectedly. The move is aimed at easing the maritime tension in this area. However, Ren Xiaofeng said that China should hold bilateral discussions with other countries, including the United States, before deciding on the time and place to implement CUES. In an interview with the Wall Street Journal, Ren Xiaofeng said that CUES only made some suggestions, which are not legally binding. China Navy spokesman Yang Liang declined to comment on all the questions put to Ren Xiaofeng. Ren Xiaofeng said that before making any arrangements or using hints, we must discuss it first. At present, we are just discussing the relevant rules. Whether to abide by these rules and when and where to use them remains to be discussed bilaterally. CUES is a voluntary rule, which is not legally binding. It only applies to "accidental or accidental" encounters between naval vessels and aircraft, and does not apply to the territorial waters of a country. However, US Navy officials have previously said that they hope all members of the forum will abide by the code in all areas, including disputed waters such as the South China Sea and the East China Sea. Admiral Jonathan W. Greenert, the U.S. Naval Operations Secretary, said that he had held several independent bilateral talks on how China should act when encountering a U.S. warship. He told the Wall Street Journal that he and Wu Shengli, commander of China's navy, agreed that the naval vessels of the two countries should communicate in English and greet each other politely when they meet. Grennet said that as far as he knows, China has achieved this and is more open. He also said that the relevant dialogue was friendly and extensive. Grennet said that the confrontation between the China and the Corpus cruiser was resolved, and the captain of China's new aircraft carrier, who was conducting exercises in the sea area, communicated with the Corpus by radio in fluent English. Grennet said that they are studying to formulate rules. Although it is not as formal and comprehensive as the rules of accidental encounter at sea, it is still very useful, and it can provide a basis for future related work. However, Grennet expressed the hope that China and other forum members would implement the rules of accidental encounter at sea within one year. At a meeting held in this forum on 20 12, China refused to adopt the cue on the grounds that the word "rules" implied that the cue was legally binding. China also doesn't agree to use English as a communication language.
