"The United States condemns actions by Hong Kong authorities that prompted organizers to close the June 4th Museum that commemorates the 1989 Tiananmen Square massacre," said State Department deputy spokesperson Jalina Porter during a telephone briefing as quoted by Voice of America.

"Hong Kong and Beijing authorities continue to silence dissenting voices by also attempting to erase the horrific massacre from history," Porter added.

Meanwhile, on the 32nd anniversary of the 1989 Tiananmen Square crackdown, pro-democracy Hong Kong police have arrested activist Chow Hang Tung.

Chow is vice chairwoman of the Hong Kong Alliance which organises annual vigils for victims of Beijing's deadly crackdown on democracy protesters, BBC reported.

The activist was arrested for promoting unauthorised assembly.

Hong Kong and Macau are the only places in Chinese territory where people can commemorate the deadly 1989 crackdown on pro-democracy protesters, reports BBC.
