Taiwan presidential frontrunner Tsai Ing-wen sought to reassure she’d seek peaceful relations with China if she won Saturday’s election, as Beijing again warned the self-ruled island against any moves toward independence. READ MORE: Why the elections in Taiwan matter so much – for Beijing, the region and the US Since the 2008 election of the China-friendly Ma Ying-jeou from the Nationalist Party, ties have improved rapidly, with a series of landmark trade and business deals signed and Ma held a historic meeting with Chinese President Xi Jinping in November. But Tsai and her independence-leaning Democratic Progressive Party (DPP) are looked at with great suspicion by China, which considers Taiwan a rebel province to be brought under its control, by force if necessary. The White House this week called on Taiwan and China to avoid an escalation of tensions from elections in Taiwan if the DPP wins.

China, however, warned it would not tolerate any moves by Tsai to undermine China’s sovereignty claims.

Beijing takes to mean it wants independence. The Nationalists on Friday warned the election was fundamentally about stability. Ma, the incumbent president, took to Facebook to urge people to vote for the party of “stability”. “Only the Nationalists can maintain the stability of Taiwan and peace across the strait,” Ma said. Andrew Hsia, the head of the Mainland Affairs Council, Taiwan's ministry in charge of China policy, said he believed Beijing would have “many questions about the outcome of the elections”, and that both sides could possibly liaise via a telephone ‘hotline’ that was set up late last year. In a blitz of advertisements carried in newspapers on Friday, the final day before polling begins at 8 a.m. on Saturday, the Nationalists showed pictures of an anxious looking child clutching a Taiwan flag with the words: “I hope this vote will enable us to no longer feel afraid”.
