The government on Sunday said it is misleading to chant slogans that disrespect 'One Country' and disregard the constitutional order, and that this is not in Hong Kong's interests. It made the statement after many protesters called for an end to one-party rule at the July 1 pro-democracy rally.
A former Democratic Party lawmaker, Albert Ho, said he was marching not just for democracy in Hong Kong but also for that of the country. He says the widow of the late Nobel Peace laureate Liu Xiaobo should be immediately freed.
"I joined the call for democracy, not only in Hong Kong but in China," Ho said. "And we are calling for the immediate release of Liu Xia, who has been under house arrest throughout all these years."
Ho said he thought her treatment was totally illegal, unlawful and inhuman.
"We also support the 08 Charter for the democratisation and political liberalisation of the Chinese people," he said.
Liu Xiaobo was one of the author's of Charter 08. The manifesto, published in December 2008, called for an independent legal system and the end to one-party rule
in 2009, Liu Xiaobo was arrested and sentenced to 11 years in prison. He received the Nobel Peace Prize in 2010 but died last year of liver cancer. His wife, Liu Xia has been kept under house arrest.
Several thousand people also took part in a parade on Sunday organised by a pro-government group to celebrate SAR Establishment Day.
