Tsai Ing-wen was sworn-in as the President of Taiwan on 20 May 2016. With this, she became the first woman to hold the post in Taiwan.
Before being presented the official seal, 59-year-old, Tsai swore the presidential oath in front of national flag. She succeeded outgoing President Ma Ying-jeou.
Tsai has said she will preserve the status quo in relations with China, but that Beijing must respect Taiwan's democracy.
Earlier in January 2016, Tsai led the Democratic Progressive Party (DPP) to a landslide win in parliamentary and presidential elections.
This is the only second time that DPP has won an election in Taiwan. The Kuomintang (KMT) has been in power for most of the past 70 years.
The DPP has traditionally leaned towards independence from China, and its victory has led to a cooling of cross-straits relations. China sees Taiwan as a breakaway province, which it has threatened to take back by force if necessary.
Who: Tsai Ing-wen
When: 20 May 2016
