Hong Kong police detained several pro-democracy activists gathered for the 34th anniversary of the 1989 Tiananmen Square massacre that left a still unknown number of people dead. 

The move by Chinese authorities has Taiwan worried as it fears its people would face the same restrictions as Hong Kong, which was the last Chinese-controlled territory to hold commemorations.

More than 30 human rights activists and artists were taken away by the HK police for holding vigils for the Tiananmen Square victims.

Commonly known as “June 4th”, the student-led protests at Beijing’s Tiananmen Square came to a violent halt in 1989, when Chinese military tanks opened fire, crushing and arresting protesters.

Now, Taiwan is the “only Chinese society” that freely allows remembrances, Chinese scholar and former Tiananmen organizer Wu Renhua said.
