According to American media reports, the country's third most powerful politician, Speaker of the House of Representatives of the US Congress, Nancy Pelosi, will visit Taiwan in August.
It has not been announced exactly when Ms. Pelosi will visit Taiwan, but the level of reaction in China to the news is unprecedented.
Chinese government officials have warned the Americans that the visit amounts to a violation of China's sovereignty and will prove that the US is abandoning its 'one-China' policy.
Asked by reporters, Chinese Foreign Ministry spokesman Zhao Lijian said on Monday,
China will take strong measures to "protect sovereignty and territorial integrity". "Any consequences will be borne by the United States," he said.
The Ministry of Foreign Affairs usually talks about foreign relations in China. But the threat of military action against the US Speaker's proposed visit has been heard from the country's Ministry of Defense.
Chinese Defense Ministry spokesman Tan Kefei told the China Daily newspaper on Tuesday that the Chinese People's Liberation Army (PLA) will not sit idly by when Nancy Pelosi visits Taiwan, and that they are "fully prepared" for any eventuality.
Why is China so angry?
It is not that former American officials or politicians do not visit Taiwan once in a while. A few days ago, former Trump administration Secretary of State Mike Pompeo also visited Taipei.
But Nancy Pelosi is one of America's most powerful politicians. His position is after the President and Vice President. He is a very influential leader of the ruling Democrats.
He has always been seen as staunchly anti-China in US political circles. He is very vocal about China's human rights situation. He visited Tiananmen Square while visiting China. His contacts with exiled Chinese dissidents are well known.
As a result, China sees this plan of such a person to go to Taiwan as a deliberate provocation by the American government.
In particular, many observers believe that the current context of China's domestic politics - the visit of Nancy Pelosi at this time has created discomfort at the top level of Chinese power.
The crucial Congress of the Chinese Communist Party is just a few weeks away - where President Xi Jinping is expected to seek approval for a third term in power.
"Speaker Pelosi's visit at this time may be viewed as an insult by Mr. Xi and the party leadership," Suzanne L. Shark, a former senior US State Department official who has also written a book on Chinese politics, told the New York Times.
"This sense of humiliation may lead President Xi to make a reckless show of force," said Suzanne Shark. This analyst felt that "it would be right to postpone the visit now without risking a conflict."
Taiwan has always been considered an integral part of China, and it is impossible for any ruling Chinese politician to take any kind of loose position on Taiwan. If that is the case, he will definitely have to fall into the party's co-panel.
China is concerned about the way President Biden's administration's diplomatic relations with Taiwan's government are increasing after he took office. Just last April, six members of the American Parliament made a surprise visit to Taiwan. President Biden himself has said at least three times in the past year that America will not hesitate to intervene militarily if Taiwan is attacked.
China is both angry and worried about this. The Chinese have voiced their concerns in the series of contacts between the two governments since the start of the Ukraine war.
However, China sees Nancy Pelosi's planned visit as fuel to the fire.
