Events marking 35 years since troops ended peaceful protest with deadly violence are banned in China and Hong Kong

Chinese and Hong Kong authorities have arrested or put under surveillance several dissidents before the anniversary of the Tiananmen Square massacre this week, according to human rights groups.

On 4 June it will be 35 years since Chinese soldiers shut down a weeks-long peaceful protest with violence, killing anything from several hundred to several thousand people.

Annual vigil replaced by pro-Beijing carnival but some still manage to mark massacre amid heavy police presence

For the past three years, Hong Kong authorities have gone to great lengths to stop people from lighting candles in Victoria Park and publicly commemorating the Tiananmen Square massacre – an annual tradition tens of thousands of residents had kept alive for three decades since the bloody crackdown in 1989.

This year, the city took it a step further. On Sunday, in place of a mass vigil was a patriotic carnival held by pro-Beijing groups, celebrating the city’s return to Chinese rule with food booths, and dance and music performances. Colourful banners urged carnival goers to “taste the joy”. Instead of candles, volunteers handed out plush toys.

Police say four arrested for ‘seditious’ acts while a further four taken away on suspicion of breaching the peace

Hong Kong police detained eight people, including activists and artists, on the eve of the 34th anniversary of China’s Tiananmen Square crackdown, a move that signals the city’s shrinking freedom of expression.

Police said in a statement late on Saturday that four people had been arrested for allegedly disrupting order in public spaces or carrying out acts with seditious intent. Four others were taken away for investigation on suspicion of breaching public peace. Authorities did not immediately respond to an email seeking comment late on Saturday.

Prosecutors said Chow Hang-Tung, Tang Ngok-kwan and Tsui Hon-kwong were under foreign influence but refused to say who it was

A Hong Kong court has jailed three former members of a group that organised annual vigils to mark the 1989 Tiananmen Square crackdown in China.

Chow Hang-tung, 38, a prominent Hong Kong pro-democracy activist and former vice-chairperson of the Hong Kong Alliance in Support of Patriotic Democratic Movements in China, was among those convicted by a magistrate’s court. The two others were Tang Ngok-kwan and Tsui Hon-kwong.
