Domestic spending has increased and the government will accelerate large project investment to help growth, Arkhom Termpittayapaisith told a Radio Thailand programme.
Southeast Asia's second-largest economy expanded a weaker-than expected 2.6% last year, lagging that of others in the region as its tourism sector just started to pick up.
Headline inflation should return to the central bank's target range of 1% to 3% this year, helped by government measures and lower food prices, Arkhom said.
A baht exchange rate of 34 to 35 per dollar is helpful for export prices despite falling export volumes, he added.
