Taiwan's Tsai Ing-wen sworn in as first female president
Tsai Ing-wen, 59, swore the presidential oath in front of the national flag, before being presented with the official seal, reports the BBC .
According to the source, Ms Tsai, seen as an unassuming but determined leader, led the Democratic Progressive Party (DPP) to a landslide win in elections in January.
In her speech she focused on Taiwan's democracy and freedom - saying it's every Taiwanese person's responsibility to safeguard this.
According to the source, this is a clear message to Beijing that Taiwanese people cherish these characteristics of their society and their self-rule more than economic ties with China, even if the mainland is the island's biggest trade partner and export market.
