This past year’s unrest in Hong Kong - crowds opposing Beijing interference in HK governance - was certainly a big factor in the minds of many Taiwanese voters. The reelection of President Tsai Ing-wen was viewed as good news by the beleaguered residents of Hong Kong.
Secretary of State Mike Pompeo congratulated Tsai, and added:
The United States thanks President Tsai for her leadership in developing a strong partnership with the United States and applauds her commitment to maintaining cross-Strait stability in the face of unrelenting pressure.The “pressure” to which Pompeo refers is of course from Beijing. It is safe to conclude Tsai’s re-election was not viewed favorably there. Taiwan has been operationally independent of Beijing for over 70 years.
