Exports, a key driver of Thai growth, will this year be supported by a recovery in global demand, vaccine distribution and stimulus measures in several countries, the ministry said in a statement.
Shipments rose for the first time in eight months in December, up 4.71% from a year earlier, the fastest growth rate in 22 months, the ministry said. A Reuters poll forecast a fall of 2.4% in exports.
"The December exports showed a good sign," ministry official Pimchanok Vonkorpon told a briefing, adding shipments of durable goods rose and global demand increased, which reflected a recovery in the real economic sector.
The export gains were helped by higher shipments of cars and car parts, computers and rubber products. Excluding gold, exports would rise 5.04% in December.
Demand from key markets was mostly higher, with exports to the United States up 15.7% year-on-year and to China up 7.2%.
However, exports may not rise much in the first quarter because of last year's comparative base but should show a good recovery for the full year, Pimchanok said.
Imports in December increased 3.62% from a year earlier, but slumped 12.39% in the whole of 2020.
Thailand had a trade surplus of $960 million in December and $24.5 billion in the full year.
