Toyota Motor Corp. said production at one of its main factories in China remained halted Wednesday because of a strike at a supplier, the latest Chinese labor action to hit a Japanese carmaker in recent weeks.

Honda Motor Co., which has repeatedly been forced to suspend production in China due to strikes, also said it halted operations there again as a fresh walkout disrupted parts supplies.

Toyota's plant in southern Guangzhou, which represents about half of Toyota's total capacity in China, remained shut after the strike forced the world's top automaker to suspend production a day earlier.

The latest shutdown occurred at GAC Toyota Motor Company Ltd., which can produce 360,000 cars, including the Camry, annually at full operation. Toyota has a total Chinese capacity of about 800,000 vehicles at five plants.

"Production remains suspended. We don't know when we can resume operations," said Toyota spokesman Hideaki Homma in Tokyo.

The factory was closed down after a strike began at a supplier run by Japanese parts-maker Denso Corp.

Denso workers demanding higher wages have refused to work since Monday, said Denso spokesman Yu Matsuda from the company's headquarters in the city of Toyota, Aichi Prefecture.

Denso held wage negotiations with workers, Matsuda said, but declined to give details. Denso's plant, which employs 1,100 workers, makes fuel injectors for engines.

Meanwhile, Honda said production at one of two auto assembly plants at joint venture Guangqi Honda Automobile Co. was suspended. Honda said it was unclear when the plant would resume production.

The shutdown was due to a shortage of parts caused by a strike, but Honda declined to give further details, including the name of the affected parts supplier.

The suspended plant, which makes the Accord sedan and Fit hatchback, has production capacity of 240,000 vehicles per year.
