Relations between the world's top two economies have deteriorated in recent months, with both sides locked in fierce recriminations over trade disputes and the origins of the coronavirus pandemic, AFP wrote.
China's latest move comes days after Washington announced new restrictions on staff working for Beijing's foreign missions, such as a requirement to seek approval for university visits or meetings with local officials.
"The Chinese side has recently sent a diplomatic note announcing reciprocal restrictions on the US Embassy and consulates," the ministry said in a statement.
It added that the unspecified countermeasures will apply to all US Embassy and Consulate staff, including the Consulate-General in Hong Kong and its personnel.
"It must be stressed that these measures are China's legitimate and necessary response to the erroneous US moves," the ministry said, urging the US to "immediately correct its mistakes" and lift the earlier curbs.
A tit-for-tat dispute over foreign missions flared up in July when Washington ordered the closure of the Chinese Consulate in Houston, prompting Beijing to shutter the American presence in Chengdu.
Washington's restrictions will force Chinese diplomats to seek US permission to hold cultural events involving more than 50 people outside mission grounds.
They also require embassy social media accounts to be publicly identified as being affiliated with the Chinese government.
