“The office of Amnesty International Hong Kong Section would cease its operations on October 31, 2021, and its website and social media pages would stop updating with immediate effect. Thank you for your support over the years,” the human rights group wrote.

Meanwhile, another Amnesty office in Hong Kong, which focuses on regional affairs, will close by this year’s end. The group had earlier said that it may move its regional operations to Taipei, Seoul or Tokyo, among others. Amnesty already has offices in Bangkok and Colombo.

Anjhula Mya Singh Bais, chairwoman of Amnesty's international board, said in a statement earlier that a crackdown under the city’s national security law has forced at least 35 groups to disband this year.

"This decision, made with a heavy heart, has been driven by Hong Kong's national security law, which has made it effectively impossible for human rights organizations in Hong Kong to work freely and without fear of serious reprisals," she said.

"The environment of repression and perpetual uncertainty created by the national security law makes it impossible to know what activities might lead to criminal sanctions," she added.
