Taiwan has been voting for its next president and parliament with the future of relations with China at stake.
Nationalist President Ma Ying-jeou, who is seeking a second term, enjoys a slight lead in opinion polls.
He has touted the success of his pro-China economic policy. His re-election would point towards Taiwan deepening economic integration with the mainland.
But his big rival, Tsai Ing-wen of the Democratic Progressive Party, fears the self-ruled island could be in danger of giving up too much of its sovereignty.
China still views Taiwan as a breakaway province, to be taken back by force if necessary.
In hard economic times for Taiwan, the gap between rich and poor, rising house prices and unemployment have also been key election issues.
