BEIJING - Spokesperson for the Chinese Ministry of National Defense Jiang Bin on Monday denounced the Japanese side for hyping up China's regular military training as a so-called security threat, saying that it will never work for Japan to evade the real issue, to divert attention, or to recriminate.

Jiang made the remarks in response to a comment from the Japanese side about a recent flight training of Chinese carrier-based aircraft.

Explaining the incident, Jiang said that on Dec 6, PLANS Nangchang (101) of the naval task group led by PLANS Liaoning notified the Japanese side that the task group would conduct aircraft carrier-based flight training, with Japanese Ship JS Teruzuki (116) confirming reception of the message.

Later on, PLANS Nangchang (101) again notified the Japanese side that the training was expected to start from 3:00 pm and last for about six hours, mainly to the south of the carrier, with JS Teruzuki (116) again confirming reception of the message, he said.

Against this backdrop, Japanese fighter jets still intruded into the training zone multiple times to harass the Chinese side, the spokesperson said, emphasizing that the Japanese side shall bear all the responsibility for endangering flight safety.

In doing so, the Japanese side has once again lied to its own people and misled the international community by hyping up a regular military training of the Chinese side as a so-called security threat and portraying itself, the real provoker, as a victim, he said.

Jiang urged the Japanese side to squarely face up to the crux of the current difficulty in China-Japan relations, and earnestly reflect on and rectify its wrongdoings.

"Those despicable moves and political manipulation to evade the real issue, to divert attention, or to recriminate will never work," he added.

Jiang also responded to another media query about memorial activities held across China on the 12th National Memorial Day for Nanjing Massacre Victims.

Describing the Japanese invasion and slaughter in Nanjing on Dec 13, 1937 as "heinous crimes," Jiang urged the Japanese side to deeply reflect on the atrocities it committed against peoples of Asian countries, including China, and stop all wrong actions in distorting and whitewashing its history of aggression.

Urging Japan to eliminate militarism

In another press conference, Chinese Foreign Ministry spokesperson Guo Jiakun said on Monday that all countries have the responsibility and obligation to urge Japan to thoroughly eradicate the vestiges of militarism, calling for joint efforts to safeguard the outcomes of World War II victory and the post-war international order.

Guo made the remarks after China had received a batch of Russian-provided evidence related to the infamous Unit 731, a Japanese germ-warfare unit that operated during World War II.

On Dec 13, the National Archives Administration of China published a batch of declassified Russia-provided archives on Soviet interrogations of the Japanese Unit 731 in Khabarovsk. The archives, containing interrogation records of Unit 731 members and investigation reports on the unit's crimes, once again lay bare Japan's notorious germ warfare during its aggression against China.

The archive copies once again show that Unit 731 has committed monstrous crimes against humanity, which are backed by irrefutable evidence and must not be denied, Guo told a regular press briefing.

According to the archives, during the aggression, the Japanese military conducted various live human experiments, including experiments with germ, frostbite, corrosive liquid and erosive gas, Guo pointed out. He added that among the victims, there were not only the Chinese people, but also people from the Soviet Union and the Korean Peninsula.

The interrogation records disclosed for the first time show that the confession of Kiyoshi Kawashima, former head of Unit 731's bacterial production department, and other Japanese war criminals detailed the Japanese military's large-scale use of biological weapons in China in 1940, 1941 and 1942, and the records prove that the application of the experiments in the war aimed at the large-scale destruction of humans, Guo said.

He further noted that the trial records in Khabarovsk - supporting and adding more proofs to the files kept by China - together with the site of Unit 731 in China, clearly demonstrate how the unit committed crimes in China and proved that the germ warfare was a premeditated, organized, top-down and systematic state crime.

Besides in China, the Japanese military established Unit Oka 9420 in Singapore in 1942, conducted illicit human experiments and waged germ warfare in Southeast Asian countries, Guo said. "Their atrocities will be condemned to perpetual infamy," he added.

It is alarming that, despite these undeniable facts, right-wing forces in Japan continue to vehemently deny, downplay, or even whitewash acts of aggression and crimes against humanity, Guo noted, adding that amnesia of history means betrayal, and denial of responsibility spells repetition of crimes.

"All countries have the responsibility and obligation to urge Japan to thoroughly eliminate the remnants of militarism, so that such tragedies are never repeated. Together, we must safeguard the outcomes of the victory in World War II and the post-war international order, and jointly uphold the hard-won peace and stability in the world," the spokesperson said.
