The Hong Kong media reported that speaking at a seminar on April 29, 2017, Wang Zhemin, legal chief of the central government’s liaison office in Hong Kong, said that the “one country, two systems” policy under which Hong Kong is guaranteed a high degree of autonomy for half a century may be scrapped if it becomes a tool to confront Beijing. He said  the Basic Law, referred only to the capitalist system and did not mean Beijing’s sovereignty over the city could be changed afterwards. Earlier, the outgoing Hong Kong Chief Executive Leung Chun-ying said the autonomy Hong Kong was enjoying was authorised by Beijing and was not “full autonomy”, and the careful implementation of the governing formula was the best arrangement for both Hong Kong and the nation.
