China - In a video clip allegedly released by a Chinese government committee, the group warned that China will "use nuclear bombs continuously" if Japan interferes with a future invasion of Taiwan.

Chinese human rights activist Jennifer Zeng (54) shared the video on her Twitter channel with added English subtitles.

According to Zeng, the video originated from officials of the ruling Chinese Communist Party who uploaded the clip to the Chinese social media network Xigua, which is run by TikTok developer ByteDance. The party celebrated the 100th anniversary of its founding earlier this month with a huge spectacle celebration.

The threat is most likely a response to Japan's deputy prime minister Tarō Asō (80), who stated in early July that Japan would defend the island nation of Taiwan, located east of China, in the event of a Chinese invasion.

Taiwan is an independent state, but is considered by the People's Republic of China to be part of Chinese territory.

Zeng claimed the shared clip "is an excerpt from a longer video of the Chinese Communist Party's military channel," and was also shared on the official account of the Politics and Law Committee of Baodi City. As of Monday, they had both since been removed.

The video states: "If Japan dares to intervene with force – even if it only deploys one soldier, one plane, and one ship – we will not only return reciprocal fire, but also start a full-scale war against Japan. We will use nuclear bombs first."

The video continued as it took a look back at Chinese history.

"Our country is in the midst of a major change that has not been seen in a century, and all political policies, tactics, and strategies must be adjusted and changed in the midst of such a major change in order to protect the peaceful rise of our country," its voiceover said.

It explained that Japan would be the "exception" to China's "commitment not to use or be the first to use nuclear weapons." The promise came after their successful detonation of the bomb in 1964, when the People's Republic became the fifth nuclear power during the Cold War to declare that it would renounce first use of its nuclear weapons in the event of a military conflict or crisis.

"Japan is the only country in the world that has been hit by atomic bombs," the video pointed out, as it threatened this time around, the country "will get twice the result with half the effort."

It also said Japan would realize it cannot afford the price of war, or to rashly send troops to the Taiwan Strait.

"We are warning Japan and informing the world that if Japan interferes militarily in our domestic affairs, including the unification of Taiwan by the mainland, nuclear weapons will surely be used against Japan, and will be used continuously, until its unconditional surrender," the mysterious clip stated.
