A member of China's organisation overseeing relations with Taiwan has come under ridicule from Chinese netizens for calling the island's new president Tsai Ing-wen "emotional" and "extreme"because she is a single woman without children.

"As a single female politician, she is unburdened by love, and lacks the constraint of family or concern for children," Wang Weixing, a military analyst and a board member of the Association for Relations Across the Taiwan Straits, wrote in the International Herald Leader newspaper, which is under China's state news agency Xinhua.

"In political style and strategy, often she tends to be emotional, personal, and extreme. In terms of political tricks, she considers strategy less, tactical details more, and short-term goals are paramount, while long-term goals are less taken into account."

The attack came days after Tsai, Taiwan's first female president, took the oath of office at the presidential palace in Taipei.

Wang's long and blistering op-ed also accused Tsai of intending to pursue "hidden independence" for Taiwan. It disappeared from some portals on Wednesday (May 25) and the link to the newspaper's website failed to load.
