China's exports surged 21 percent on-year in January, the government said Wednesday, after figures showed the Asian giant had overtaken Germany as the world's leading exporter in 2009.

Exports totalled 109.475 billion US dollars for the month, solidifying the turnaround recorded in December, according to figures released by the General Administration of Customs.

The figure however showed a 16.3 percent drop month-on-month.

China's trade surplus reached 14.17 billion US dollars in January, the figures showed.

On Tuesday, Germany surrendered to China the title of top global exporter it had claimed in 2003, as the country's trade suffered its sharpest slump since 1950, according to government data.
