Germany's trade surplus widened to 18.7 billion euros in May, official data showed yesterday, as external demand improved from a month ago.

Exports were up 1.1 per cent to 113.9 billion euros from April, while imports eased back 0.5 per cent to 93.4 billion euros.

Foreign trade is crucial for the German economy and is being closely monitored as the commercial climate deteriorates amid an escalating trade conflict between the United States and China.

EU nations are not immune to tariff barriers imposed by the US administration during uncertain times for the global economy.

Monday's positive trade surplus data came along with figures showing a small rebound in industrial production for May.
