China's foreign affairs spokesman on Thursday voiced opposition to any interference of the country's domestic affairs while commenting on the U.S. Secretary of State's remarks about Internet freedom.

Foreign Ministry spokesman Ma Zhaoxu told a regular press briefing that China will strengthen communication and exchanges with other countries on Internet related issues and jointly promote sound development of the Internet, while it opposed foreign interference in its domestic affairs with the use of Internet freedom as a pretext.

Commenting on remarks by U.S. Secretary of State Hillary Clinton on Tuesday concerning China's Internet censorship, Ma said China administrates the Internet according to relevant laws and regulations, which are in line with international practice.

He added that the Chinese government supports and encourages the development of Internet, and ensures its citizen's freedom of speech according to laws, including that on the Internet.

By the end of 2010, 457 million Chinese, or 34.3 percent of the country's total population, had become Internet users.
