China barred a radical Hong Kong pro-democracy activist and lawmaker from a visit to the earthquake ravaged province of Sichuan on Friday, despite his earlier inclusion on an official list of delegates.
Leung Kwok-hung, a strident pro-democracy activist known as “Longhair”, had been traveling on a coach with other Hong Kong legislators to the airport, when he was told his travel permit application had been rejected at the last minute, on suspicions he was planning protests in China during the 3-day trip.
“Some Chinese netizens thought Leung Kwok-hung might carry out certain actions … and so under such circumstances, the provincial government decided not to let him travel,” explained Rita Fan, the president of Hong Kong’s legislative council.
