Despite the falling sale outlook, Toyota Motor Thailand Company has no plan to shut down plants in Thailand after its parent Toyota Motor Corporation (Japan) halted its production in 12 factories in Japan, the company's executive said Wednesday.

"The company will adjust the production plan to deal with the market this year, as the sales figure is expected to slump 20 percent," Toyota Motor Thailand's executive vice president Suparat Sirisuwannakura was quoted as saying by Bangkok Post's website on Wednesday.

Also, the company will terminate additional investments in its major projects in Thailand until the economic condition improves. Other measures include a reduction on production and overtime payment, and early retirement program would also be an alternative for contract employees, said Suparat.

In a bid to survive the global economic crisis, Toyota Motor Corporation's headquarter in Japan decided 11 days ago to suspend the production in 12 of its domestic plants.

As Thailand's largest auto manufacturer, Toyota Motor Thailand was established in October 1962, with a current registered capital of 7.52 billion baht ( 214.9 million U.S. dollar). The company's workforce is 13,500, with 119 dealers and 292 showrooms, according to the company's website.

Toyota Motor Thailand has three production plants in the country, with their production capacity respectively at 250,000 units, 200,000 units and 100,000 units a year.

In Thailand, the auto industry has largely contributed to the domestic economic expansion for years, with the know-how and technology transferring from parent firms abroad and improvement of Thai workers' skills in this sector.
