China is to relax its policy of restricting most couples to have only a single child, state media say.
In future, families will be allowed two children if one parent is an only child, says the Xinhua news agency.
The one-child policy already exempts rural dwellers and ethnic minorities.
The move comes after this week's meeting of a key decision-making body of the governing Communist Party. Other reforms include the abolition of "re-education through labour" camps.
