The post, published in both Chinese and English, referred to a CIA effort to recruit Chinese spies as “yet another farcical performance”.
It was the first time that the MSS, which has become increasingly active on social media, has responded to the advertisements – two Chinese-language videos posted by the CIA on social media last month.
The videos were intended to exploit possible dissatisfaction among Chinese officials with the ruling Communist Party leadership and encourage them to leak secrets to the United States.
A public recruitment drive, launched by the CIA last October, posted instructions online on how to safely contact the US spy agency in the hope of attracting informants from China, Iran and North Korea.
Last month, Chinese foreign ministry spokesman Lin Jian condemned the recruitment drive, calling it “a serious violation of China’s national interests and a blatant political provocation”.
