Tsai Ing-wen

Tsai Ing-wen won the presidential election as the Democratic Progressive Party candidate, becoming Taiwan's first female president. Her victory signaled a shift away from Ma's pro-China policies.

Under Tsai's leadership, Taiwan became the first country in Asia to legalize same-sex marriage. The law was passed after a constitutional court ruling and a public referendum.

After China imposed a national security law on Hong Kong, Tsai's government condemned the move and offered support to Hong Kong residents. This further strained cross-strait relations.
