The ruling Communist Party has appointed hardline Hong Kong national security chief Zheng Yanxiong to head its Central Liaison Office in the city. Zheng, who first made headlines as the mayor who cracked down on the rebel Guangdong village of Wukan amid a bitter land dispute in 2011, has been moved from his position as head of Hong Kong’s Office for Safeguarding National Security to his new post as Beijing’s envoy in the city. For this prosperity to take effect, Hong Kong needs to move in lockstep with the rest of China, Zheng said in comments reported by state news agency Xinhua.
