On October 27, 2015 (September 15, 2015 lunar calendar), the US Navy came to the South China Sea to make trouble. The US Navy destroyer USS Lassen is said to have entered within 12 nautical miles of China's artificial islands in the South China Sea. According to a report by Reuters on October 26, the US Department of Defense announced that it would send a guided missile destroyer to China within 24 hours to sail within 12 nautical miles of the artificial islands and reefs in the South China Sea. Subsequently, CNN reported that the US warship has entered within 12 nautical miles of the islands and reefs in the South China Sea. According to reports, the US military dispatched the USS Lassen guided missile destroyer to sail in the waters around Subi Reef and Mischief Reef in the Nansha Islands, and will also send P-8A reconnaissance aircraft to patrol the waters. The P-3 Orion reconnaissance aircraft may also be involved, and further patrols will be carried out in the coming weeks. The Chinese foreign minister said that we are verifying this matter. If it is true, we advise the US side to think thrice before acting rashly and not making trouble out of nothing. According to the Global Times, Chinese warships followed the US warship when it sailed within 12 nautical miles of islands and reefs in the South China Sea. It is believed that the "Lassen" was followed by the flagship of China's South China Sea Fleet, the Kunming ship of the latest 052D Aegis ship hull number 172. According to the US government, the "Lassen" guided-missile destroyer has been cruising around the South China Sea for four weeks recently, during which it has encountered Chinese naval vessels several times, but the "Lassen" has not entered within 12 miles of islands and reefs in the South China Sea before. The last time the US claimed to be within 12 miles of islands and reefs in the South China Sea was in 2012, before China had even begun construction there. The US Navy is cruising around and the Chinese Navy is not idle. The Chinese Navy's elite 052D Aegis ship Kunming is believed to have monitored, tracked, and warned the Lassen in the South China Sea. The US military claims to patrol near islands and reefs in the South China Sea to "safeguard freedom of navigation," and US Navy ships are also sailing around the world. Coincidentally, the Chinese Navy's Aegis ship Jinan is now on a round-the-world mission and is now heading for the United States after leaving the port of Lisbon on the 21st. The Chinese Navy's training ship Zheng He has just left Pearl Harbor and is on its way to the port of Zhenhai, South Korea. According to foreign media reports, on September 3, when China held a military parade to celebrate the 70th anniversary of the victory of the Anti-Japanese War, five Chinese Navy ships sailed from the Bering Strait into the coast of Alaska (within 12 nautical miles). At this time, US President Barack Obama was inspecting the state of Alaska. It is believed that this is the first time the Chinese Navy has appeared in the waters of the Bering Strait. A Pentagon spokesperson said that the Chinese warship is legally transiting. As a blue sea army, the Chinese Navy has increased the frequency of missions in the far sea in recent years. In addition to the escort missions in the Gulf of Aden widely reported by the media, according to public reports, the Chinese Navy has carried out more than ten far-sea missions in 2015 alone, including but not limited to: the 052C Jinan ship participating in the round-the-world voyage In April, the 20th batch of Chinese Navy escort taskforce went to the Gulf of Aden to perform escort missions, and then the taskforce made a full global voyage, and visited India, circumnavigated the world, and visited Sudan, Egypt, Denmark, Finland, Sweden, Poland, Portugal, the east coast of the United States, Cuba, Mexico, Australia, Timor-Leste, Indonesia and other countries. In May, the Chinese Navy Yulin ship conducted the "China-Singapore Cooperation-2015" maritime exercise with the Singapore Navy in Singapore, during which live ammunition was fired. In May, the Chinese Navy's amphibious landing ship Jinggangshan joined a number of coast guard ships in Malaysia to participate in the fourth joint disaster relief exercise of the Eastern Regional Forum. In June, the Japanese Ministry of Defense announced that the Japanese Maritime Self-Defense Force had found a fleet composed of the Type 052B guided missile destroyer Wuhan (hull number 169), the Type 071 dock landing ship Jinggangshan (hull number 999) and the Type 904 supply ship Fuxianhu (hull number 888) about 700 kilometers south of Miyako Island. This small formation is only part of the Chinese military's military exercise in the Western Pacific. A large number of Chinese naval ships and various types of combat aircraft such as the Fighter 11, Bomber Six G and Yun 8 have held large-scale military exercises in the Western Pacific. In August, four ships of the Chinese Navy went to Russia to participate in the Sino-Russian "Joint Maritime-2015 (II) " military exercise. The two sides sent more than 20 ships of various types, more than 20 aircraft, 40 amphibious equipment, and more than 500 marines to the exercise. China and Russia will conduct drills in joint air defense, joint anti-submarine, joint anti-ship, joint defense and other subjects, and conduct joint three-dimensional landing drills for the first time. In September, the Chinese Navy's Yuncheng ship went to Indonesia to participate in the 70th anniversary of independence celebrations. In September, the Chinese Navy's 170 Lanzhou ships, 575 Yueyang ships and 866 Peace Ark hospital ships visited Malaysia to participate in the China-Malaysia "Peace and Friendship-2015" military exercise. The above-mentioned actions are only a small part of the Chinese Navy's far-sea operations this year, considering that the military's actions will not be fully disclosed, and the general patrols except for visits to other countries are not easy to be reported in the newspapers. The operation of the US military, which is not tense between China and the United States, has caused an uproar in public opinion, but this is only a small wave between the high-level exchanges between the Chinese and US governments and the military. On October 19, 27 US Navy captains visited China's first aircraft carrier, the Liaoning. This is the first large-scale visit to China by US front-line commanders, and the first time the Liaoning is open to foreign front-line commanders. Then Wu Shengli, a member of the Central Military Commission and the commander of the Navy, met with a visiting US Navy captain delegation in Beijing on October 22. Wu Shengli pointed out that the current Sino-US naval relations have entered the best period in history. The two sides have worked together to pass the "Rules for Unexpected Encounters at Sea". High-level interactions and exchanges have been frequent, joint exercises and training have been continuously deepened, and mechanism consultations have been fruitful. Vessel visits and front-line troop exchanges have been pragmatic and in-depth, and exchanges and communication have become more mutual trust and effective. In particular, the navies of the two countries have successfully organized consultations on the "Code of Conduct for Sea and Air Encounters" between China and the United States and promoted the signing of a memorandum of understanding on the code, effectively implementing the consensus reached by the leaders of the two countries. This relationship is hard-won and is the result of the joint efforts of officers and soldiers of the two navies at all levels. In the next step, a delegation of Chinese naval front-line commanders will also visit the United States. In the future, the exchanges between the front-line At the Xiangshan Forum held in October, Fan Changlong, Vice Chairperson of the Central Military Commission, said that even on issues involving territorial sovereignty, we will never resort to force lightly, try to avoid misfire, and always resolve differences and disputes through friendly consultation with the parties directly concerned. The construction of islands and reefs in the South China Sea is mainly for civilian purposes, which will not affect the freedom of navigation in the South China Sea, but will also provide better public services for navigation and production in the South China Sea. In June this year, Fan Changlong, Vice Chairperson of the Central Military Commission, led a delegation to visit the United States, met with US Secretary of Defense Carter, and visited the nuclear-powered aircraft carrier at the California Naval Base and the Fort Hood Military Base in Texas and other military installations. At the Shangri-La Summit held at the end of May, Sun Jianguo, the deputy chief of general staff of the Chinese People's Liberation Army, had a friendly exchange with the US defense secretary, and also refuted the US remarks that China is hindering the freedom of navigation in the South China Sea. The US military went to the South China Sea to show its muscles, and China responded strongly at the diplomatic and military levels. More importantly, the Chinese Navy has also increased the frequency of missions around the world in recent years. The United States claims to safeguard freedom of navigation in the South China Sea, and the Chinese Navy can also safeguard freedom of navigation in many parts of the world.
