TAIPEI -- Taiwanese President Tsai Ing-wen on Thursday registered for the Democratic Progressive Party's presidential primary, setting up a contest with former Premier Lai Ching-te ahead of next year's elections.
Lai, also known as William Lai, is a more vocal advocate of an independent Taiwan separate from China. He unexpectedly registered Monday. Lai served as premier under Tsai but stepped down a few months ago in the wake of the ruling DPP's crushing defeat in local elections.
