TAIPEI, Taiwan (AFP) — Taiwan’s President Tsai Ing-wen won a landslide victory yesterday as voters delivered a stunning rebuke of Beijing’s campaign to isolate the self-ruled island and handed its first female leader a second term.

Tsai, 63, was greeted by thousands of jubilant flag-waving supporters outside her party headquarters, hailing a result which looks set to infuriate China.

“Today we have defended our democracy and freedom; tomorrow let us stand united to overcome all challenges and difficulties,” she told the cheering crowd.

Official results showed Tsai secured 57 per cent of the popular vote with a record-breaking 8.2 million ballots, 1.3 million more than her 2016 victory.

Her main rival Han Kuo-yu, from the China-friendly Kuomintang, racked up 39 per cent and conceded defeat.

The result is a blow for Beijing, which views Taiwan as part of China and has made no secret of wanting to see Tsai turfed out.

Over the last four years it ramped up economic, military and diplomatic pressure on the self-ruled island, hoping it would scare voters into supporting Tsai’s opposition.

But the strong arm tactics backfired and voters flocked to her Democratic Progressive Party (DPP), fuelled in part by China’s hardline response to months of huge and violent pro-democracy protests in Hong Kong.

In the United States, Taiwan’s primary military ally, Secretary of State Mike Pompeo saluted Tsai’s “commitment to maintaining cross-Strait stability in the face of unrelenting pressure”.

Tsai pitched herself as a defender of liberal democratic values against the increasingly authoritarian shadow cast by China under President Xi Jinping.

Beijing has vowed to one day retake the island, by force if necessary. It loathes Tsai because she refuses to acknowledge the idea that Taiwan is part of “one China”.

Her campaign frequently invoked Hong Kong’s protests as a warning of what might lie ahead should China one day take control of Taiwan.

During her victory speech Tsai said she was committed to dialogue with China’s leaders and wanted peace.

But she called on Beijing to halt its sabre-rattling towards Taiwan and respect the idea that only the island’s 23 million inhabitants can decide its future.

“Today I want to once again remind the Beijing authorities that peace, parity, democracy and dialogue are the keys to stability,” Tsai said.

“I want the Beijing authorities to know that democratic Taiwan and our democratically elected Government will never concede to threats”.

But China is also Taiwan’s largest trade partner, leaving the island in a precariously dependent relationship.

After Tsai’s speech, Chinese State media carried a short statement from the mainland’s Taiwan Affairs Office saying Beijing “opposed any form of Taiwanese independence splittist attempts”.

Office spokesman Ma Xiaoguang later told Xinhua State media that Beijing continues to “uphold the basic principles of ‘peaceful reunification’ and ‘one country, two systems’ and the one-China principle”.

While strongly opposing Taiwanese independence, “we are ready to work with Taiwan compatriots” to promote peaceful ties and “advance the process toward the peaceful reunification of the motherland”, Ma said.

Foreign Ministry spokesperson Geng Shuang told Xinhua that he hoped the international community will “understand and support the just cause of Chinese people to oppose the secessionist activities for ‘Taiwan independence’ and realise national reunification”.

Han, the 62-year-old mayor of the southern city of Kaohsiung, favoured warmer ties with China — saying it would boost Taiwan’s fortunes — and accused the current Administration of needlessly antagonising Beijing.

But his campaign struggled to gain momentum or escape the perception that he was too cosy with Taiwan’s giant neighbour.

Turnout in the poll was 75 per cent, a jump of nearly 10 per cent from Tsai’s first presidential election victory four years ago.
