Access to an online museum dedicated to the victims of Communist China’s 1989 crackdown on pro-democracy in Beijing’s Tiananmen Square was cut by Hong Kong police.

The Hong Kong Alliance in Support of Patriotic Democratic Movements of China, the organisers of annual June 4 vigils in the global financial hub, announced the opening of  last month. The website operated independently from the Alliance, it said.

Hong Kong users have not been able to access the website from the city since Thursday without using virtual private networks. Internet service provider PCCW declined comment. Providers HKBN and 3HK did not respond to requests to comment.

It is a disgraceful act to erase historical memory, the online museum said in a statement.

Hong Kong police said it could not comment on individual cases, but said national security legislation states that “police may require service providers to take actions to prohibit electronic messages posted on electronic platforms that are likely to endanger national security.”

While the internet in mainland China is heavily censored and access to foreign social media platforms and news sites is blocked, Hong Kong residents have so far enjoyed greater freedoms under the “one country, two systems” framework agreed when the former British colony returned to Chinese rule in 1997.

The first censorship case under the security law Beijing imposed on the city in 2020 emerged in January when authorities blocked access to protests-related website HK Chronicles.

The June 4th Museum’s physical location in Hong Kong closed in June over a licensing probe and has since been added to a list of assets and bank accounts frozen by authorities as part of a national security investigation against The Alliance.

The organisation said last week it would disband after police accused it of being “an agent of foreign forces,” raided the museum’s premises, and charged the group with inciting subversion under the national security law.

The Alliance, which denies the allegations, was the latest of dozens of civil society bodies to fold over the past year.

Its leaders Albert Ho and Lee Cheuk-yan, like dozens of other pro-democracy activists and politicians, are in jail over large anti-government protests that roiled the city in 2019 and also face national security charges.

Hong Kong traditionally holds the world’s largest annual June 4 vigil, although police banned the last two events over coronavirus concerns. Mainland China bans commemorations and heavily censors the topic.


Chinese Communist Party was never judged and condemned for this crime

Communist China has never provided a full account of the 1989 crackdown. Officials gave a death toll of about 300 days afterwards, but rights groups and witnesses say thousands may have been killed.
