The Hong Kong government has proposed to grant the city's leader powers to extradite fugitives to mainland China. Rights activists say China critics could be subject to torture and unfair prosecution there.
Thousands of people in Hong Kong took to the streets on Sunday to protest a government plan to change the city's extradition laws. Rights activists and business leaders fear the proposed amendments would erode personal freedom and Hong Kong's status as an international business hub.
In February, the Hong Kong government proposed that the city's chief executive should be given powers to send fugitives and suspects to jurisdictions not covered by existing arrangements, including to mainland China and Taiwan.
Current arrangements exclude China because of its poor legal and human rights record.
The government plans to present the amendments to legislators on Wednesday.
