During the spread of the coronal epidemic, China established a new administrative district in the South China Sea, and also exacerbated air force activities around Taiwan.In the East China Sea, the activities of the Chinese Navy and Maritime Police reached unprecedentedly.This not only further deteriorated the public opinion of Japan, but also stimulated the Japanese nationals' request to cancel the official visit of the President of Xi Jinping, which has been postponed.

The official statistics of the Japanese Maritime Security Agency show that the activities of the Chinese Maritime Police on the surrounding waters around the Diaoyu Islands (China -called Diaoyu Islands) of the Chinese Police have increased. Since April 14, 2020, every day, a Chinese vessels will drive into the adjacent sea area. OneThe cumulative number of times has also exceeded 100 times in a row.This is the most frequent movement since China has trained the ship into the Saitar island in December 2008.

Moreover, from July 2nd to 3rd, the Chinese bars who entered the territorial sea stayed for 30 hours, which is very rare and long.The Japanese government proposed a serious protest to the Chinese government, but regarded the Chinese government, which regarded the islands of Jiange as the inherent territory of China, but did not accept the Japanese protest.

On the other hand, from the perspective of the Chinese Navy's movement, the Japanese Self -Defense Force confirmed that from June 18th to 20th, foreign submarines were adjacent to the sea in Japan's overseas overseas on the overseas area around Amami.The Minister of Defense Kono Kono has made it clear that this is a Chinese submarine, and said that under the various situations of the China Sea, the South China Sea, or the borders of China and India, and the pressure on the one -country and two systems in Hong Kong, it is necessary to clearly speculate on speculationThe intention of the Communist Party of China.Kono Kono said it will continue to observe China's actions.

China's active activities in the East China Sea are not due to the expansion of the crown disease.In 2019, although the media pointed out that Japan -China relations have improved, there is a tendency to increase the Chinese bars in the adjacent waters of Jianpang Islands; it can be said that after the expansion of the crown disease epidemic, it is only the continuation of its actions.In 2019, the Japanese Air Self -Defense Force's emergency rise to the Chinese Air Force military aircraft surged.

The pressure of the Chinese army and the Chinese maritime police has also affected Japanese public opinion and policies.On July 3rd, the Japan's ruling party ’s Democratic Democratic Party’ s diplomatic group passed a opinion requesting the cancellation of Chinese President Xi Jinping's visit to Japan. Although the direct reason is the Hong Kong issue, the situation around the East China Sea is also one of the important factors.

Regarding territorial issues, China has a Chinese position. From the perspective of China, there may be no problems with Chinese activities and behaviors.EssenceIf the Chinese party recognizes that the response of the other party is a new threat and further improves the pressure, it will fall into a typical security predicament.

Before and after the expansion of the crown disease epidemic, the changes in China's performance in the surrounding waters, even if China has the Chinese claims, will be recognized by neighboring countries and regions that this is an act of raising tensions.Remember, East Asia's prosperity is based on the stability of military security.
