Isuzu Motors Ltd. is preparing to double its heavy-duty truck production capacity in Thailand this year in hopes of increasing exports to Southeast Asian markets.

The company recently invested further in its heavy truck plant in Thailand's central province of Chachoengsao to double its annual production output of 25,000 to 26,000 vehicles. Thailand-produced trucks mostly cater to the domestic market at present, according to Toshiaki Maekawa, president of Isuzu's local distributor, Tri Petch Isuzu Sales Co.

The carmaker expects to start exporting heavy trucks 2 tons or larger in loaded weight, both built-up and knocked-down, to meet huge demand in Southeast Asian countries in the near future.
