On the morning of December 13th, Senior Colonel Wu Qian, director of the Information Bureau of the Ministry of National Defense and spokesman of the Ministry of National Defense, released news about the recent military-related issues. Reporter: Japanese Prime Minister Shi Pomao recently delivered a policy address, saying that the current international order is facing major challenges. Chinese aircraft carriers sail in the waters close to Japan's territorial waters, and carrier-based aircraft have conducted thousands of take-off and landing trainings in the Pacific Ocean; Based on the national security strategy, Japan will greatly strengthen its defense forces. What is China's comment on this? Wu Qian: The so-called "China military threat" was hyped by the Japanese side only to cover up its usual trick of getting rid of the shackles of the peaceful constitution and returning to the old road of military expansion. As a matter of fact, the diplomatic and defense departments of China and Japan have been maintaining communication on air and sea security issues. There is absolutely no need for the Japanese side to be jittery and nervous. The publication of these data just proves that the Japanese side has been tracking, monitoring and interfering with Chinese ships and aircraft at close range for a long time, endangering the safety of Chinese ships and aircraft and easily causing sea and air safety problems. In recent years, despite the opposition of the international community, Japan has gone further and further on the road of military expansion, which has aroused strong concern among neighboring countries and the international community. We urge Japan to draw lessons from history, be cautious in the field of military security and do more things that are conducive to maintaining regional peace and stability. China is willing to continue to maintain communication with Japan on properly handling air and sea emergencies, and hopes that Japan will move in the same direction with China, take the overall situation into consideration, take the right path, and jointly safeguard the stability of the air and sea situation and the overall situation of Sino-Japanese relations.
