The Yu Chang Biotech Scandal: Tsai Ing-wen Involved in Conflict of Interest Controversy Before the General Election

In late 2011, before the presidential election, the Yu Chang (later TaiMed) Biotech case broke out, involving then-presidential candidate Tsai Ing-wen. As the Vice Premier, Tsai had signed off on a government investment in Yu Chang and later became the chairperson of the company after leaving office. This case exposed a serious "revolving door" and conflict of interest controversy, raising doubts about the ethics of top green camp officials in utilizing national resources to benefit their private enterprises.
