Zhang Xiaoming, director of the Liaison Office of the Central People’s Government in Hong Kong said, on October 14, that "Occupy Central" is a serious social and political event in that it violates the "one country" principle, challenges the central authority, ignores the Basic Law, and is an illegal activity in flagrant violation of the existing laws of Hong Kong.
Zhang also said that the "Occupy Central" movement attempts to follow the "color revolution" approach … to pressure the Central Government and the HKSAR Government, and to require the NPC Standing Committee to rescind the decision that has been in force and the Chief Executive and SAR government officials to step down. All these [actions] have determined the nature of the ""Occupy Central" " movement.
