TAIPEI, Taiwan鈥� Voting was underway Saturday in Taiwan鈥檚 presidential election in which the island鈥檚 China-friendly Nationalist Party appears likely to lose power to the pro-independence opposition, amid concerns that the island鈥檚 economy is under threat from China and broad opposition among voters to Beijing鈥檚 demands for political unification.
The Democratic Progressive Party鈥檚 Tsai Ing-wen is poised to become the self-governing island鈥檚 first female president, returning the main opposition party to power after eight years under Nationalist President Ma Ying-jeou, who is constitutionally barred from another term.

The outcome of the contest for a majority in the 133-seat legislature remains uncertain, with independents and smaller parties posing a threat to both the Nationalists and the DPP.
A win for Tsai would introduce聽new聽uncertainty in the complicated relationship between Taiwan and mainland China, which claims the island as its own territory and threatens to use force if it declares formal independence.

鈥淭his is not about defeating the other party. This is about working to overcome the obstacles in Taiwan鈥檚 path,鈥� Tsai told supporters gathered in the rain at a final rally Friday night in front of the presidential office building in the center of the capital, Taipei.
Tsai has pledged to maintain the status quo of de-facto independence for the island of 23 million, although she has refused to endorse the principle that Taiwan and China are parts of a single nation to be unified eventually.
Beijing has made that its baseline for continuing negotiations that have produced a series of pacts on trade, transport and exchanges. Observers say China is likely to adopt a wait-and-see approach to Tsai鈥檚 presidency, but might use diplomatic and economy pressure if she is seen as straying too far from its unification agenda.
Taiwan was a Japanese colony from 1885 to 1945 and split again from China amid civil war in 1949.
Tsai鈥檚 Nationalist opponent, Eric Chu, was a late entry in the race after the party ditched its original candidate, Hung Hsiu-chu, whose abrasive style was seen as alienating voters. He has trailed Tsai by double digits in the latest polls.
China has largely declined to comment on the polls, although its chief official for Taiwan affairs this month warned of potential major challenges in the relationship in the year ahead.
Tsai supporters appeared confident that ties with China would weather a change in government.
鈥淎s long as Tsai doesn鈥檛 provoke the other side, it鈥檚 OK,鈥� said former newspaper distribution agent Lenex Chang, 66, who attended Tsai鈥檚 rally. 鈥淚f mainland China democratizes someday, we could consider a tie-up,鈥� he added.
