According to the South China Morning Post, on June 10, 2014, the State Council of the People’s Republic of China issued an unprecedented white paper on the “one country, two systems” issue in Hong Kong. "The white paper on Hong Kong shows Beijing’s determination to maintain control amid the debate over political reform.” “By issuing the paper, Beijing has sought to establish its unquestioned authority over Hong Kong as residents debate the meaning and the flexibility of the ‘one country, two systems’ concept.” It stated, "The high degree of autonomy that Hong Kong has enjoyed is subject to the central government’s authorization. There is no such thing called ‘residual power’ for the special administrative region." It also "warned against ‘outside forces’ using the city to interfere in China’s domestic affairs.”
The paper came 10 days before the “Occupy Central” activities, the activists of which are calling for greater democracy, i.e., calling for an unofficial referendum for the 2017 election of the chief executive.
