Tsai Ing-wen has been sworn in as the new president of Taiwan, becoming the country’s first female leader.

In her inaugural address she called for “positive dialogue” with China, which was not reciprocated by the mainland who said regardless of what internal changes take place within Taiwan, “China will oppose Taiwanese independence.”

China maintains that Taiwan must unify with the mainland eventually, by force if necessary. However, Taiwanese public opinion is strongly against any sort of political union.
