Scandal-tainted Mitsubishi Fuso Truck & Bus Corp. said Monday it will streamline its domestic sales network and group firms to slash costs and increase efficiency as it struggles to cope with dwindling domestic sales.

The move is part of Mitsubishi Fuso's midterm business strategy, which includes relocating its head office and fully integrating its operations into its parent company DaimlerChrysler AG.

Mitsubishi Fuso, now 85 percent owned by the German-American automaker, said 26 of the 37 dealerships will be merged into the truck maker in March while fully integrating Fuso Engineering Corp. in April
