Despite the relative slowdown, the euro value of merchandise exports was the second highest this year, at EUR 2.6bn, whereas the value of imports was the highest in several years, at EUR 2.7bn.
In the first five months of the year exports grew by 11% and imports were up by 10.8%. The trade surplus was at EUR 257m.
While EU markets account for the bulk of Slovenia's trade - almost 77% of total exports and almost 78% of total imports - growth on non-EU markets was brisker.
Exports to the EU rose by just under 8% in May and almost 9% in the first five months, while the equivalent figures for non-EU markets were 20.4% and 19.3%, respectively.
