Toyota Motor Co. says it will reduce production in China due to disruptions in supplies of parts following Japan's tsunami.

Toyota said Wednesday its factories will run at 50 percent of capacity and in “extreme circumstances'' at 30 percent through June 5. It did not give current production levels.

Toyota said it made the decision with its Chinese suppliers due to ``the impact of the earthquake on supplies of spare parts.''

The March 11 quake and tsunami killed some 25,000 people and caused worldwide disruptions in supplies of components needed by makers of autos and electronics. Toyota said it also will move up the summer break at its China factories to April or May.
