According to the French Customs, France's trade deficit widened to €4.575 billion in March from €3.623 billion in February.
February's figure was revised down from a deficit of €3.4 billion.
The increase of a deficit was driven by energy imports and lower aerospace exports.
Imports rose due to strong recovery in energy and due to strong demand for automobiles, capital goods and intermediate goods, while exports increased due to higher sales of automotive, pharmaceuticals, metals and electrical and electronic equipment.
