Taiwan saw off China’s military six decades ago when its forces bombarded offshore Taiwanese islands and that resolve to defend the homeland continues to this day, President Tsai Ing-wen told a visiting group of U.S. academics on Tuesday.

Tensions between Taiwan and China have spiked over the past month following the visit to Taipei by U.S. House Speaker Nancy Pelosi. China staged war games near Taiwan to express its anger at what it saw as stepped up U.S. support for the island Beijing views as sovereign Chinese territory.

Meeting the delegation from Stanford University’s Hoover Institution at her office, Ms. Tsai referenced China’s month of attacks on the Taiwan-controlled islands of Kinmen and Matsu that sit off just off the Chinese coast which started in August 1958.

“Sixty-four years ago during the Aug. 23 battle, our soldiers and civilians operated in solidarity and safeguarded Taiwan, so that we have the democratic Taiwan today,” Ms Tsai said, using the common Taiwanese term for that campaign, which ended in stalemate with China failing to take the islands.

“That battle to protect our homeland showed the world that no threat of any kind could shake the Taiwanese people’s resolve to defend their nation, not in the past, not now, and not in the future,” Ms. Tsai added.

“We too will show the world that the people of Taiwan have both the resolve and confidence to safeguard peace, security, freedom and prosperity for ourselves.”

In 1958, Taiwan fought back with support from the United States, which sent military equipment like advanced Sidewinder anti-aircraft missiles, giving Taiwan a technological edge.

Often called the Second Taiwan Strait Crisis, it was the last time Taiwanese forces joined battle with China on a large scale.

The United States, which ditched formal diplomatic relations with Taipei in favour of Beijing in 1979, remains Taiwan’s most important source of arms.

“As Taiwan stands on the front line of authoritarian expansionism we continue to bolster our defence autonomy, and we will also continue to work with the United States on this front,” Tsai said.

China’s drills near Taiwan have posed a threat to the status quo in the strait and across the region, and democratic partners should work together to “defend against interference by authoritarian states”, Ms. Tsai added.

Taiwan’s government says that as the People’s Republic of China has never governed the island it has no right to claim it or decide its future, which can only be set by Taiwan’s 23 million people.
