The "constitutional reform of Hong Kong is China's domestic affair which brooks no interference from the outside", Chinese foreign ministry spokesman Qin Gang told reporters at a regular briefing.
Qin was responding to comments made by State Department spokeswoman Jen Psaki in Washington yesterday supportive of pro-democracy protesters in Hong Kong, a semi-autonomous region of China.
"The United States supports universal suffrage in Hong Kong in accordance with the Basic Law and the aspirations of the Hong Kong people," Psaki told reporters, referring to Hong Kong's mini-constitution.
Only two or three will be allowed to stand for election. Democracy activists say the rules mean China will be able to ensure that only pro-Beijing candidates can contest the vote.
Britain handed Hong Kong back to China in 1997 under an agreement which allows civil liberties not seen on the mainland, including free speech and the right to protest.
"To safeguard the lasting prosperity and stability of Hong Kong serves the common interests of the international community including the US."
China hopes the international community will see the issue "from a positive and objective perspective", Qin added.
Asked to react to the continuation of a British parliamentary inquiry into Hong Kong, Qin underlined that the region was no longer under London's control.
"It is not the Hong Kong of before 1997," he said, adding that its matters are part of China's domestic affairs.
