Nancy Pelosi, speaker of the US House of Representatives and a vocal critic of China in recent years, will arrive in the country on Sunday for a one-week visit, the Wall Street Journal reported. Pelosi’s trip was announced by state media and confirmed by an official at the US embassy in Beijing. According to Western diplomats in the capital, the speaker will lead a Congressional delegation to Beijing and Shanghai and give the keynote address at an environmental energy forum. Pelosi is best known in China circles for unfurling a banner in Tiananmen Square in 1991, two years after the brutal government crackdown on pro-democracy protesters. She subsequently opposed the US establishing normal trade relations with China, visited the Dalai Lama, and suggested President George W. Bush boycott the Olympic opening ceremony. Pelosi’s visit comes just 10 days before the 20th anniversary of the Tiananmen protests.
