Top officials and political figures in Hong Kong have welcomed the central government's white paper that reviewed the "one country, two systems" principle since its adoption in 1997.

The White Paper on the Practice of the "One Country, Two Systems" Policy in the Hong Kong Special Administrative Region (HKSAR) was issued by the Information Office of the State Council on Tuesday. It was translated into seven languages.

The paper highlights the importance of fully and accurately understanding and implementing the policy of "one country, two systems", as this policy has faced "new circumstances and new problems".
