In 2019, Japan and China prepared for the Chinese President Xi Jinping's visit to Japan. It was considered to have improved the relationship. In addition, since the emergence of coronal virus problems, China has launched mask diplomacy, and friendly exchanges between the two countries have been promoted.However, the more frequent movements of the Chinese army around Japan are more clearly visible.

So far, on the website of the Japanese Maritime Security Agency, the activities around the Chinese Maritime Police on the East China Pavilion (China -called Diaoyu Islands) are reported every month.Obviously, Chinese bayonators are more frequent than before.On April 9, 2020, the Ministry of Defense of Japan released the emergency take -off of the Air Self -Defense Force in 2019, showing that the same situation occurred in the air.

According to a report from the Ministry of National Defense, the overall number of emergency departure of the Japanese Air Self -Defense Force's aircraft in 2019 (April to March 2020) was 947 times a year, a decrease of 52 times from last year.However, this is the third largest number in the past.It is particularly worth noting that the number of emergency take -off for Russian aircraft has decreased, and the number of emergency liters of Chinese military aircraft has increased by 37 to 675 times, accounting for 70 % of the overall.In addition, the examples of Chinese aircraft and Russian planes from the Japanese Sea to the East China Sea have also attracted much attention.

Looking at the sea, although the Chinese Maritime Police's activities around Jiange's island have declined from the end of 2017 to 2018, it has become more active since 2019. Japan has more than four times a month, and the neighboring waters have reached more than 100 times.EssenceThe Chinese Navy's activities have also become frequent.

Some people have pointed out that China has called for improving Japan's relations, and domestic public opinion has also made some changes in Japanese views.In addition, since the crown disease epidemic, the initial aid of Japanese masks and the masks from China after March have been called Meimei.Although Xi Jinping's visit to Japan is postponed, the tone of improvement of Japan -China relations has not changed.

In this process, the most surprising side of China is that Japanese society's understanding of China is still very bad.One of the reasons is that China ’s military activities around Japan, or the activities of the vessel, are a threat from China.Because of this, when the famous Japanese comedians died of crown disease, the Japanese citizens pointed the anger's finger to the original mistakes of the crown disease in China.

China has its concept of foreign policy.In terms of security and security, Japan and the United States and security will not be concessions in core interests; in addition, China cannot accept Western values.China must build a win -win relationship with countries in terms of economy. However, no matter how the improvement of these bilateral relations is promoted, as long as China puts extremely bright pressure on individual countries on the security guarantee issue, the so -called improvement of friendly exchanges, beautiful talks and other words will all will all will all will all will all will all will have words.It is considered to be extremely superficial.

Of course, maybe China will say that the data published by the Ministry of Defense and the Maritime Security Agency is incorrect.If so, why is China not disclosed its military operations and information about the sailing of the ship within the possible scope?

China has strongly criticized China's threat theory. Indeed, overseas media often reported a preconceived report on China. However, if China itself cannot be disclosed in information, foreign countries will publish a variety of data, and the outside world will also be based on the outside world.These data form a cognition of China.

From the perspective of public diplomacy, if it is not disclosed to a certain degree of information, or if it does not explain its obligations, at least Japan's perception of China will not change, and it will even continue to deteriorate.
