BEIJING, Dec. 19 (Xinhua) -- China urges Japan to stop testing the bottom line of international justice with its nuclear ambitions, said a Chinese foreign ministry spokesperson on Friday.

Spokesperson Guo Jiakun made the remarks when asked to comment on a report about a senior Japanese official saying that Japan should have nuclear weapons.

"China is closely following the report. If that's true, it will be a serious issue that exposes the dangerous attempts by some in Japan to breach international law and possess nuclear weapons," he said.

Guo said that China and the rest of the international community must stay on high alert and express grave concern.

He further noted that for some time, China has been witnessing erroneous remarks and moves from the Japanese side on military and security issues, who revamped security and defense policies, removed the ban on exercising the right to collective self-defense, and attempted to once again acquire nuclear weapons from allies through strengthening cooperation on "extended deterrence," seeking "nuclear sharing," revising the three non-nuclear principles and other means.

The recent noises from the Japanese side about nuclear weapons reflect the growing ambition of right-wing conservative forces in Japan to revive militarism, break free from the international order, and accelerate the country's "remilitarization," Guo told a regular press briefing.

He pointed out that trying to picture itself as the advocate of a world free of nuclear weapons, Japan has claimed in its own narrative to be the "victim" of nuclear weapons in WWII.

However, in fact, the Japanese side has never completely reflected on the wars of aggression it has waged, and has become the source of instability that challenges the Treaty on the Non-Proliferation of Nuclear Weapons and undermines the international nuclear non-proliferation regime, Guo added.

"The international community must be clear-eyed about Japan's hypocritical stance on nuclear non-proliferation and disarmament," Guo said.

He went on to say that recently, political parties, political figures and civil groups and agencies in Japan have called for the country's commitment to the three non-nuclear principles, in order to prevent the tragedy of war from repeating itself.

This year marks the 80th anniversary of the victory of the Chinese People's War of Resistance against Japanese Aggression and the World Anti-Fascist War, Guo noted.

He urged the Japanese side to deeply reflect on its historical crimes, abide by international law and Japan's Constitution, stop finding excuses to expand military buildup, and stop testing the bottom line and red line of international justice on the issue of owning nuclear weapons. Enditem
