The monthly increase comes after two months of contraction, but on a year-on-year basis output has been growing since December.
Mining contracted severely, by almost 12% over the year before, and electricity, gas and water supply was broadly flat, but manufacturing proceeded apace, growing by 6.4%.
Industrial revenue grew, though at a slower pace than output. It was up 1.5% on the previous month and 3.2% higher than in the same period last year.
Inventories likewise increased, rising 1.8% at the monthly level and 6.6% year-on-year.
