BEIJING, Dec 8 (Reuters) - China's imports grew at the fastest pace in more than two years in November, fueled by its strong thirst for commodities from coal to iron ore, while exports also rose unexpectedly, reflecting a pick-up in both domestic and global demand.

The upbeat data adds to signs of a modest industrial recovery in the world's largest economies, even as China and other Asian exporters brace for a potential trade war once protectionist U.S. President-elect Donald Trump takes office.

"The improvement reflects a strengthening in global demand, with recent business surveys suggesting that developed economies are on track to end the year on a strong note," Julian Evans-Pritchard, China economist at Singapore-based Capital Economics, said in a note.

"But while global demand has recovered somewhat recently, lower trend growth in many developed and emerging economies means that further upside is probably limited."

China's November imports expanded 6.7 percent on-year, confounding expectations for a drop of 1.3 percent and the strongest gain since September 2014, data showed on Thursday.

Exports rose 0.1 percent from a year earlier, defying predictions for a 5 percent slide. Demand from all of China's major trading partners improved significantly, especially Europe and the United States, though shipments to emerging economies remained weak.

That left the country with a trade surplus of $44.61 billion for the month, the General Administration of Customs said, versus forecasts of $46.30 billion and October's $49.06 billion.

Analysts polled by Reuters had expected a more modest drop in November exports after a 7.3 percent contraction in October, while imports had been seen falling at roughly the same pace.

MAN OF STEEL

China's imports of major commodities including iron ore, crude oil, coal, soybeans and copper all surged in November, despite a sharp weakening in its yuan currency.

While some analysts have worried that sharp commodity price rises could be masking still sluggish demand, the data showed imports rose in both value and volume terms.

A government infrastructure building spree and housing rally have fueled a construction boom in China this year, spurring demand for building materials from steel bars to cement.
