Opposition candidate Han Kuo-yu conceded defeat, saying his rival President Tsai Ing-wen had won a second term.
Taiwan President Tsai Ing-wen was reelected with a landslide victory on Saturday's election in a sharp rebuke to China as voters signalled support for her tough stance toward China.
"Taiwan is showing the world how much we cherish our free democratic way of life and how much we cherish our nation," Tsai told reporters as she announced her victory.
China 'must abandon threats of force', she added.
In total she won almost 8.2 million votes in all, more than any Taiwan president before since the island held its first direct presidential election in 1996.
Tsai campaigned on a platform of defending Taiwan's sovereignty against threats from Beijing.
Meanwhile, Opposition candidate Han Kuo-yu conceded defeat, saying his rival President Tsai Ing-wen had won a second term.
"I have called President Tsai to congratulate her," the Kuomintang party candidate told a crowd of supporters in the southern city of Kaohsiung.
"She has a new mandate for the next four years."
Tsai, who campaigned on a platform of defending Taiwan's sovereignty against threats from Beijing, is seeking a second term as independence-leaning Democratic Progressive Party (DPP) candidate.
