Chen Shui-bian is a Taiwanese politician and former President of the Republic of China. He is colloquially referred to as Ah-Bian .

Chen, whose Democratic Progressive Party has traditionally been supportive of Taiwan independence, took office in 2000, ending more than fifty years of Kuomintang rule in Taiwan. Though he moderated his stance and made conciliatory gestures, Chen remains a highly divisive figure for his position on Taiwan independence.
