Former Deputy Chief of Staff General Jack Keane expressed concern about China's "aggression" before holding a virtual summit with President Biden.

China claimed on Tuesday that President Biden condemned Taiwan’s independence from a communist country, but warned the United States to "play with fire" in the South China Sea.

After Biden and Chinese President Xi Jinping held a virtual summit that lasted for several hours, a new round of threats emerged. This is the most extensive meeting of world leaders since Biden took office.

In a reading after the meeting, Chinese officials stated that Biden reiterated that the United States supports the one-China policy and claimed that the US president "does not support'Taiwan independence'."

Since the government of the Republic of China moved to the western Pacific islands in the conflict with the Chinese Communist Party (CCP) in 1949, Taiwan and China have had a complicated history. 

Taiwan is regarded as a sovereign country, but it is officially recognized as part of the one-China policy by China, the United Nations and the United States. 

China made it clear on Tuesday that it fully intends to "completely unite" the island with mainland China and threatened to take action if troops try to prevent this.

"If the'Taiwan independence' separatist forces provoke us, force us to act, or even cross the red line, we will have to take resolute measures." "On this issue concerning China's sovereignty and territorial integrity, there is no room for compromise."

The United States and its Western allies support Taiwan’s security. There are reports that as China’s aggression in the region escalates, the United States is working hard to strengthen its defenses in the Indo-Pacific region. 

The White House did not refute China's claim that the United States continues to recognize the one-China principle, but the tone is far less soothing.

The White House said in a statement after the meeting: "President Biden emphasized that the United States remains committed to the'One China' policy, guided by the Taiwan Relations Act, the three joint communiqués and the six guarantees." 

However, the statement also stated that the United States "strongly opposes" any actions that change the "status quo" of the region or "undermine peace and stability across the Taiwan Strait."  

Although both countries have expressed support for the one-China policy, they have different views on what it means for the region. 

"The United States and China have two different approaches to the concept of one China," Zach Cooper, a senior researcher at the American Enterprise Institute, which specializes in American Asian strategies, told Fox News. "Beijing advocates the one-China principle, while Washington adheres to the one-China policy. This is very different."

Cooper, who served in the Department of Defense and served as an assistant to the White House National Security Council during the Bush administration, said that such differences in views may mean that geopolitical conflicts will continue to occur in the region.

He added: "China and the United States hold two different views on the meaning of one China... This issue will be difficult to resolve because neither side is likely to adjust their practices in the short term."

Biden and Xi Jinping agreed to have candid discussions on the complex topics facing the two countries, but did not seem to come up with a policy-based solution.
