Isuzu Motors Ltd. may accelerate its restructuring moves under the industrial revitalization law to take advantage of tax breaks and other favorable treatment, company sources said Thursday.

The struggling maker of trucks and commercial vehicles announced its new three-year business plan Wednesday. Its largest shareholder, U.S. auto giant General Motors Corp., and main creditor banks will provide financial aid.

In line with the plan, it is considering streamlining businesses and launching an early retirement program to cut 3,700 jobs and bring the size of its parent-only workforce to 8,700.
