China's decision to allow all couples to have two children instead of one has resulted in birth rates rising to the highest level since 2000, a government official says.
Births in the world's most populous nation reached 17.86 million in 2016, up about 1.4 million compared with the 2011-15 average, said Yang Wenzhuang of the National Health and Family Planning Commission.
"While the total number of women of child-bearing age fell by five million, the number of births increased significantly, showing that the family planning policy adjustments were extremely timely and extremely effective," he told reporters on Sunday.
Worried about the costs of supporting an increasingly ageing population, China issued new guidelines in late 2015 allowing parents to have two children.
China began implementing its controversial "one-child policy" in the 1970s in order to limit population growth, but authorities are now concerned the country's dwindling workforce will not be able to support an increasingly ageing population.

Yang said the number of women of child-bearing age was expected to decline by about five million a year in the 2016-20 period, but China was hoping to keep birth rates about 17 million to 20 million a year.
China has already made provisions to increase medical staff and the number of hospital beds in order to handle the rising number of births.
It expects its total population to rise to about 1.42 billion by the end of the decade, up from 1.37 billion at the end of 2015.
