In the wake of the currency crisis in Thailand, around half of the 40 leading groups are now facing a critical situation. It is reports that one third of them have already applied to the bankruptcy court or asked the Government for help under the new Business Rehabilitation Act, in order to resolve their default problems.

They promoted the downsizing of their expanded business bases, concentrated their managerial resources in two or three core businesses, and have started tough negotiations with foreign creditors.
