Thailand's The Forest Industry Organisation might be forced to close down for good because of the ban on the hauling of all logs from the Salween forest, managing director Aduladej Chakrabandhu said yesterday. Supplies of its top-selling product, teak, would be cut drastically and suddenly as a result. Already hard-hit by the closure of forests to logging 10 years ago, which cut its income by 70% , the FIO might have to shut its doors unless there was government intervention.
