President Joe Biden has announced that the United States will militarily intervene if the People's Republic of China decides to invade Taiwan, according to reports.

What are the details?

During a Monday press conference in Tokyo, Biden said that the United States military will help Taiwan defend itself against China if necessary.

A reporter asked the president, "You didn't want to get involved in the Ukraine conflict militarily for obvious reasons. Are you willing to get involved militarily to defend Taiwan if it comes to that?"

"Yes. That's the commitment we made," Biden responded while delivering in remarks alongside Japanese Prime Minister Fumio Kishida.

The president added that China should not take Taiwan "by force."

"[It] is just not appropriate," he said.

A White House spokesperson told Fox News that the Biden administration's One China policy "has not changed."

"As the president said, our policy has not changed," the spokesperson said. "He reiterated our One China Policy and our commitment to peace and stability across the Taiwan Strait. He also reiterated our commitment under the Taiwan Relations Act to provide Taiwan with the military means to defend itself."

Fox News noted that America's "One China policy" states that the U.S. recognizes the People's Republic of China as the "sole legal government of China, but only acknowledges, without endorsing, Beijing's claim that Taiwan is part of China."

What else?

Chinese Foreign Ministry spokesperson Wang Wenbin said that he was unhappy with and opposed to Biden's remarks.

"China has no room for compromise or concessions on issues involving China’s core interests such as sovereignty and territorial integrity," Wang said.

In October, Biden issued similar remarks and said that the U.S. would defend Taiwan in the event of a Chinese invasion, to which a ministry spokesperson warned, "No one should underestimate the strong resolve, determination, and capability of the Chinese people to safeguard national sovereignty and territorial integrity. China has no room for compromise."
