The top U.S. representative in Taiwan, Sandra Oudkirk, said on Friday that the United States is committed to helping Taiwan defend itself amid heightened tensions between Taipei and Beijing.

Speaking to reporters at her first news conference since assuming her post in July, she described U.S. relations with Taiwan as "rock-solid".

"The United States has a commitment to help Taiwan provide for its self-defence," said Oudkirk, who heads the American Institute in Taiwan, the de facto U.S. embassy in the absence of formal diplomatic ties.

Her remarks come as tension between Taiwan and China, which has not ruled out taking the democratically ruled island by force, has escalated in recent weeks.

In a statement to Reuters, the Chinese foreign ministry said it is opposed to Oudkirk's comments and urges the United States to be aware of the sensitive nature of the Taiwan issue.

"Don't play with fire, or it will severely impact China-U.S. relations and the peace and stability of the Taiwan Strait," the statement said.

While the United States, like most countries, has no formal ties with the Chinese-claimed island, it is its most important international backer and main arms supplier. President Joe Biden's administration has moved to restate that support, to the anger of Beijing.

Washington is required by law to provide Taiwan with the means to defend itself but it has long followed a policy of "strategic ambiguity" on whether it would intervene militarily to protect Taiwan in the event of a Chinese attack.

When asked if the United States would come to Taiwan's defence if China attacked, Oudkirk said the policy towards Taiwan has been clear and remains unchanged, citing several U.S. laws governing its relations with Taiwan.

A recent increase in Chinese military exercises in Taiwan's air defence identification zone are part of what Taipei views as stepped up military harassment by Beijing.

Taiwan Defence Minister Chiu Kuo-cheng said earlier this month that military tensions with China are at their worst in more than 40 years.

In an interview with CNN that aired Thursday, Taiwan President Tsai Ing-wen confirmed that a small number of U.S. forces are in Taiwan to train Taiwanese soldiers.

When asked for more details on the presence of U.S. forces on the island, Oudkirk declined to comment on specific operations or training.

"We engage with our partners in Taiwan on a routine basis to assess vulnerabilities, to assess ways we can support Taiwan in mounting its own self-defence," she said.

The U.S. Secretary of State Antony Blinken on Tuesday urged all United Nations member states to support Taiwan's "robust" participation in the U.N. system.
