The government credits the one-child policy introduced in 1980 with preventing hundreds of millions of births and helping lift countless families out of poverty. But the strict limits have led to forced abortions and sterilizations by local officials, even though such measures are illegal. Couples who flout the rules face hefty fines, seizure of their property and loss of their jobs.
The update on birth limits was one sentence long, with details on implementation left to the country's family planning commission. It was unclear what might happen to children born in violation of rules, whose existence have been concealed and thus lack access to services.
Cai said some experts estimate the policy change might result in 1 million to 2 million extra births in the first few years. But he said the figure might be significantly lower because of growing acceptance of small families.
