BEIJING, March 4 (Xinhua) -- The behavior of playing up the security risks in Chinese products by some U.S. officials is interference in economic activities by political means, a spokesperson for the annual session of China's top legislature said Monday.

It is against the rules of the World Trade Organization, and disrupts international market order based on fair competition, a typical practice of double standards that is neither fair nor moral, said Zhang Yesui, spokesperson for the second session of the 13th National People's Congress, at a press conference.
