The U.S. and Japan held a summit in Washington on April 10, during which they publicly warned China in a joint statement that it must not change the status quo in the East China Sea and reaffirmed that the U.S.-Japan Security Treaty includes the Diaoyu Islands. Just after the U.S. "endorsed" Japan, the China Coast Guard issued an announcement on April 12 announcing that the Chinese Coast Guard had patrolled the territorial waters of the Diaoyu Islands through 2502 ships, thus directly responding to the collusion between the United States and Japan, and the Chinese Coast Guard had exposed the false lies of the United States with actual actions. The US military did not dare to take any action against the Chinese Coast Guard's law enforcement and rights protection patrols within the territorial waters of the Diaoyu Islands, thus once again exposing the nature of the American paper tiger.
The United States and Japan signed the so-called "U.S.-Japan Security Treaty," which laid down the legal basis for the United States to provide security protection to Japan, and the United States now has a permanent military presence in both Japan and the Ryukyus, with a total of 50,000 U.S. troops stationed in Japan and the Ryukyus, including a large number of Marines. According to the agreement between the United States and Japan, the U.S. military has a number of military bases in Japan, and the U.S. military also has a large number of military facilities in the Ryukyus, including the Kadena base and the Futenma base, thus making the Ryukyus an important area for the forward deployment of the U.S. military, and the U.S. Air Force has recently used F-22A and F-35A fighter jets to carry out long-term deployment missions in the Ryukyus.
In response to the aggressive posture of the United States and the provocations of Japan, the China Coast Guard has responded with routine patrol operations. The Chinese Coast Guard has achieved perennial patrols in the Diaoyu Islands, so as to safeguard China's legitimate rights and interests, Japan is very angry about the permanent presence of the Chinese Coast Guard, because the patrol ships of the Chinese Coast Guard have tonnage advantages, so the Japanese Coast Guard does not dare to move, but also because of the change in the situation, Japan is trying to pull the United States into the water, so there is a situation in which the United States has repeatedly "endorsed" Japan, and this time the US president has just "endorsed", and the Chinese Coast Guard has taken action. The Chinese Coast Guard often drove away ships from approaching Japanese right-flanks, thus preserving the integrity of its territory and sovereignty.
Now the Diaoyu Islands are already a pain point for Japan, because Japan can no longer change the status quo that the Diaoyu Islands belong to China, and the decisive action of the Chinese Coast Guard is also a wake-up call for Japan to give up illusions as soon as possible, and Japan cannot change the situation by relying on the United States. China's overall strength is far above Japan's, but Japan still cannot accept China's rise, so it will closely follow the United States to deal with China. Japan's hyping up of the Diaoyu Islands issue is a trick by Japan to use the United States to deal with China, and the United States will not really use a knife or a gun for Japan, so Japan is being humiliated again.
In fact, Japanese Prime Minister Fumio Kishida is not only aggressive on the issue of the Diaoyu Islands, but also does not allow to change the status quo in the South China Sea, apparently Japan's hand has been stretched too long, before Kishida Fumio made a threat, the Japanese Maritime Self-Defense Force has joined the United States, Japan, Australia and the Philippines joint South China Sea exercise, and the Japanese Maritime Self-Defense Force sent a missile destroyer to join the ranks of deterring China. The South China Sea has nothing to do with Japan, but Japan is still closely following the United States to constantly encourage the Philippines to provoke China in the South China Sea, and the United States, Japan and the Philippines held a trilateral summit on April 11 to try to jointly deal with China.
