This came after photos showing a foetus and the mother, Feng Jianmei, shocked web users.
She was made to undergo the procedure in Shaanxi province in the seventh month of pregnancy, local officials said after investigating.
Chinese law clearly prohibits abortions beyond six months.
The Ankang city government said it decided to suspend three officials in Zhenping county following initial investigations. It also urged the county government to conduct a thorough review of its family planning operations, said Xinhua news.
China has long denied that its vast army of local family planning officials are using abortion to enforce the country’s one-child policy.
In this case, though, there has been a rare admission that her pregnancy was terminated against her will, and now action will be taken against certain officials.
What has made the difference appears clear.
Minutes after the abortion, a family member posted on the internet a photograph of Feng Jianmei’s aborted foetus, clearly formed at seven months, lying next to her on a hospital bed and the image went viral.
It is a classic illustration of the challenge posed to China’s one party system by the internet.
On Thursday night, the city officials apologised to Ms Feng, 27, and her family, the report said.
She was ”forced to terminate her pregnancy” at a hospital in Zhenping on 2 June, said Xinhua.
Officials in Zhenping county claimed she agreed to the abortion because she was not allowed to have a second child by law. She already has a daughter, born in 2007.
But activists said she was forced into the abortion as she could not pay the fine for having a second child.”
