The four Thai firms seeking approval to import logs from Burma cannot accept the conditions the Forestry Department has set for the granting of permits, an executive for one of the traders said yesterday. Taweesak Mongkolkosol, managing director of TMS Intertrade & Services Co, a partner of Polpana Co, said he was speaking on behalf of all four companies. "It's not just us who can't accept the terms. The other three can't either," he insisted.
