China on Thursday urged the British government to stop interfering in Hong Kong affairs.

Foreign Ministry spokesperson Geng Shuang made the remarks at a daily press briefing in response to a half-year report on Hong Kong released by the British government recently.

"Hong Kong is a special administrative region of China. Hong Kong affairs belong to China's domestic affairs and any foreign countries has no right to interfere," said Geng. "We demand that the British side be cautious in words and deeds, and stop interfering in Hong Kong affairs."

Geng said the policy of "one country, two systems" has scored remarkable achievements since Hong Kong's return to China in 1997.

The policies of "one country, two systems," "Hong Kong people governing Hong Kong," and a high degree of autonomy have been fully implemented, he said.

The central government has strictly followed the Constitution and the Basic Law of the Hong Kong Special Administrative Region (SAR) of the People's Republic of China, and given full support to the chief executive and the SAR government in governance according to law, he said, adding that the Hong Kong people enjoy full rights and freedom in accordance with law.

China has strong confidence and unswerving will to continue implementing the "one country, two systems" policy, the spokesperson said.
