He emphasized that developments in Hong Kong and Macao since their return to the motherland tell us that to sustain the long-term prosperity and stability of Hong Kong and Macao and further advance the cause of “one country, two systems,“ it is imperative to observe the following four principles. First, we should stay committed to the fundamental policy of one country and fully deliver the benefits of two systems. We should place our country's sovereignty, security and development interests above everything else; we should implement the overall jurisdiction of the central authorities; and we should not deviate from this commitment under any circumstance. At the same time, we should respect the differences between the two systems, fully ensure a high degree of autonomy of the two SARs of Hong Kong and Macao, and continue to fully, faithfully and resolutely implement the policy of “one country, two systems,“ under which the people of Hong Kong administer Hong Kong and the people of Macao administer Macao, both with a high degree of autonomy. We should see that this policy is not changed, deviated from, bent or distorted.
