China criticized the US senate bill, said – China may have an impact on the political foundation of the US

China's foreign ministry has accused the United States of violating its commitment to the "one China" principle and of interfering in internal Chinese affairs. The US Senate Foreign Relations Committee has approved a new bill that could significantly increase US defense support for the island of Taiwan. 

Chinese Foreign Ministry spokesman Mao Ning told reporters in Beijing that China has filed serious complaints with Washington over the law, which still needs the approval of the US House and President Joe Biden to become law. The One China Principle is the political foundation of Sino-US relations, he said.

He said that if the bill continues to be discussed and taken forward or signed into law, it will be a Sino-U.S. conflict. 

China claims the self-governing democracy of Taiwan as its territory and has not ruled out annexing the island by force if necessary. The sides split after civil war in 1949 and have no official relationship, with China also cutting off informal contact after the 2016 election of independence-leaning Taiwanese President Tsai Ing-wen. 

Under its "One China" policy, the United States recognizes the government in Beijing, while allowing informal relations and defense ties with Taipei.

The Taiwan Policy Act of 2022, approved by the committee on Wednesday, sets out to support Taiwan's security and its right to self-determination, providing billions of dollars in defense funding to enhance "counter-intervention capabilities"

Democratic Sen. Bob Menendez, who co-authored the bipartisan bill with Republican Sen. Lindsey Graham, stressed that its focus is on deterrence and that China should not see it as a threat.

"The bill we are approving today makes it clear that the United States does not seek war or escalate tensions with Beijing," he said in a statement.

We are carefully and strategically mitigating the existential threats facing Taiwan by increasing the cost of taking the island by force so that it becomes too risky and unacceptable. 

The bill received committee approval at a time when tensions between Beijing and Washington over Taiwan were already high since US House Speaker Nancy Pelosi's visit to Taipei last month.

This prompted China to launch missiles into the Taiwan Strait and mobilize large numbers of ships and warplanes for exercises around the island.

China sees high-level foreign visits to the island as interference in its affairs and a de facto recognition of Taiwan's sovereignty. 

The Biden administration has insisted that the United States' "One China" policy has not changed.Despite the lack of formal diplomatic ties with Taiwan, the US remains its strongest political supporter and source of defensive weapons, and during her visit Pelosi said she wanted to help defend the island.
