China's trade growth has rebounded strongly in a positive sign for the recovery of the world's second largest economy.
Data has shown export growth in December more than doubled from the previous month to 14%.
Imports rose 6%, up from November's lack of growth, in a sign of increasing domestic demand.
The data adds to signs China is gradually emerging from its worst economic downturn since the 2008 global crisis.
Factory output and other activity also are improving, though analysts say a recovery will be slow and weak.
