Toyota Motor Corp., the automaker most affected by the March 11 disaster, said Wednesday it will reduce auto production at all of its Chinese plants by 50 to 70 percent until June 3 due to parts supply disruptions following last month's earthquake and tsunami disaster.

The world's largest automaker said in a press release it has decided that "vehicle production in China will be carried out at 30 percent to 50 percent of normal from April 21 through June 3 due to parts supply difficulties."

According to Toyota, the slowdown will lead to a production drop of around 80,000 vehicles, impacting operations in the country it sees as a key market.
