Three core members of the Mitsubishi group are considering an additional package of support for Mitsubishi Motors Corp., including purchases of the struggling automaker's assets, sources said Wednesday.

Among additional support under study by the three group members, Mitsubishi Heavy Industries Ltd. plans to grant MMC a respite from payments for the air-conditioners and other auto parts it supplies.

Trading house Mitsubishi Corp. is considering purchasing MMC-owned land on which the automaker's head office building stands in Tokyo's Minato Ward for about 30 billion yen.

Bank of Tokyo-Mitsubishi will help MMC review its revival plan and may set aside funds for emergency loans.

Including expected loans from the Development Bank of Japan, MMC hopes to receive some 100 billion yen in additional support, the sources said.

The Mitsubishi group and other concerns provided a total of around 500 billion yen to finance MMC's rehabilitation plan adopted in May.
