China warned on Tuesday it would take necessary measures to crack down on "infiltration and sabotage activities of foreign anti-China forces", days after the CIA released videos aimed at enticing Chinese officials to leak secrets to the US.

"The US not only maliciously smears and attacks China, but also blatantly deceives and lures Chinese personnel to turn to its side, and even directly targets Chinese government officials," Foreign Ministry spokesman Lin Jian told a regular press briefing when asked about the videos.

"This is a serious violation of China's national interests and a naked political provocation."

The CIA last week released a number of videos it said were aimed at "recruiting Chinese officials to help the US". (Reuters/AFP)
