China has unwound its one-child policy, for decades a symbol of invasive and coercive government planning, but the shift has been met with a disinterested shrug from many younger couples.

"People are thinking: Why increase our burden by having another baby?" said Wu Tingting, a young mother pushing her 1-year-old daughter in a stroller on Friday in the southern city of Zhuhai.

The ruling Communist Party announced Thursday that all families in China will be eligible to have a second child, its biggest social policy shift in three decades, in a move to ease the burden of a fast-aging society at a time of slowing economic growth.
