Thai Glico, the local unit of the Japanese confectionery maker, plans to use several billion baht to restore its factory that was inundated during last year's floods.
The factory is in Bangkadi Industrial Estate in Pathum Thani province.
Managing director Jiro Watabiki expects the company's business will return to normal in the second half this year, with sales reaching 2.4 billion baht, the same level as 2010.
The factory started producing key items such as Glico's Pocky in both chocolate and strawberry flavours since April, and the products will be available at 7-Eleven convenience stores across the country this week.
It will temporarily import some products such as Pretz and Elfie to meet production shortfalls.
The Thai production unit will resume output of Pretz for sales in September, while Pocky, Choc Banana and Elfie are on the line.
Mr Watabiki said sales of Glico in Thailand last year declined to about 2 billion baht, compared with 2.4 billion earned in 2010.
But he said the flood hadn't dampened Glico's enthusiasm for investment in Thailand.
"No matter what happens, we have no plans to move out of Thailand where we have established our business for 42 years. We have many loyal Glico fans here, so we cannot leave them," he said.
Glico Thailand is an important regional production base, with 20% of the capacity exported to Asean countries.
Yesterday the company launched a new campaign called Pocky Stars Contest to welcome the return of Pocky. The campaign offers opportunities to young ladies to showcase their talents on a TV ad with the new presenter for Pocky, Monchanok "Mo" Saengchaipiangpen.
Due to the recent minimum wage hike, Glico raised the price of Pocky chocolate and strawberry flavours to 18 baht, up from 15 baht.
