The 36th anniversary of a bloody crackdown that ended pro-democracy protests in China passed like any other weekday for most Chinese.

Security was tight in Hong Kong and activists faced pressure from police on the 36th anniversary of China's bloody 1989 crackdown on pro-democracy demonstrators in Tiananmen Square, which Taiwan and the United States said must never be forgotten.

TAIPEI (Reuters) -The world will never forget China's 1989 crackdown on pro-democracy demonstrators in Tiananmen Square, Taiwan's president and the top U.S. diplomat said on the 36th anniversary of an event Beijing treats as taboo and allows no public remembrance.
