Recent visits by guests from the United States have reinforced Taiwan's determination to defend itself, President Tsai Ing-wen said today as she met the latest US lawmaker to arrive on the island in defiance of Beijing.

China, which claims Taiwan as its own territory against the strong objections of the democratically elected government in Taipei, launched military drills near the island after US House of Representatives Speaker Nancy Pelosi visited in early August.

About a week later she was followed by five other lawmakers and late yesterday Senator Marsha Blackburn touched down in Taipei.

Meeting at the presidential office, President Tsai praised the visits.

"In recent times, many public figures from a broad spectrum of US society have visited Taiwan.

"These warm acts of kindness and firm demonstrations of support have reinforced Taiwan's determination to defend itself," she said, in remarks carried live on President Tsai's social media pages.

The United States, like most countries, has no formal diplomatic relations with Taiwan, but is bound by law to provide it with the means to defend itself.

Ms Blackburn, a Republican from Tennessee who sits on the Senate Commerce and Armed Services committees, told President Tsai that the United States and Taiwan shared the values of freedom and democracy.

Ms Blackburn later told reporters on a call that Taiwan was looking for more foreign military sales (FMS) from the United States.

"They are definitely looking for more," Ms Blackburn said. "And when it comes to the FMS sales, they feel like this is moving much too slowly. The pace needs to pick up on that."

Since 2017, US presidents have approved more than $18 billion in arms sales to Taiwan, the largest portion of that coming in the second half of the Trump administration.

But new approvals have slowed under President Joe Biden, amid delivery backlogs, supply chain bottlenecks, and reports of disagreement between Washington and Taipei over what defence items the island needs.

President Tsai said fellow democracies must work together to ensure more secure and resilient supply chains, and that she was "delighted" to see Taiwanese semiconductor companies investing in the United States.

"We also look forward to working with the United States to strengthen cooperation on semiconductors and other high-tech sectors and jointly respond to the economic challenges of the post-pandemic era."

Taiwan is a major producer of chips, tight supplies of which have hit supply chains globally.

President Tsai said Taiwan would like to be "further integrated" into the Biden administration's new Indo-Pacific Economic Framework, which the island has been excluded from, and other regional economic cooperation architecture.

US legislators are not the only ones to visit. President Tsai also hosted two Japanese parliamentarians this week, and British and Canadian members of parliament are expected later this year.

"It shows Taiwan is not alone dealing with the big bully across the Taiwan Strait," Taiwan Foreign Minister Joseph Wutold reporters at a separate event, referring to China.

Beijing has never ruled out using force to bring Taiwan under its control.

Taiwan's government says the People's Republic of China has never ruled the island and so has no right to claim it, and that only its 23 million people can decide their future.
