Thailand's manufacturing production index (MPI) in June rose 4.74% from a year earlier, helped by higher production of cars and parts, sugar, air conditioners and electronics, the Industry Ministry said on Tuesday.
That compares with a 3.0% rise seen in a Reuters poll and May's 2.87% increase, which was revised down from 3.20% earlier.
Capacity utilisation was 69.04% in June, little changed from May's revised 69.82%.
The ministry expects the MPI to rise 2.5-3.0% this year, after increasing 1.58% last year.
