Exports fell an unexpected 15.0 per cent on-year in March to USD 144.57 billion, the General Administration of Customs said, while imports tumbled 12.7 percent to USD 141.49 billion.
The monthly trade surplus, which had hit consecutive records in January and February, plummeted 60.0 per cent to USD 3.08 billion.
The export decline was far off what economists had expected, with a survey by Bloomberg News projecting an increase of 9.0 per cent. The poll forecast a trade surplus of USD 40.1 billion.

In the first quarter, overall prices of China's imports fell by 9.8 per cent year on year, with those for key commodities iron ore, crude oil and refined oil dropping 45 percent, 46.8 per cent and 38.7 per cent respectively, according to Huang.
Growth slowed to 7.4 per cent in 2014, the weakest in 24 years, and the deceleration appears to have continued into this year as indicators including industrial production, consumer spending and fixed asset investment have slumped.
Beijing is trying to manage a delicate rebalancing of the economy to make growth more consumer driven and sustainable, but also making sure it does not slow so much that job growth is severely affected, which could cause popular discontent -- a key concern of the Communist Party.
