OK , have found out a bit more about the topic but as far as I can see this was a matter discussed by the W.H.O and not purely a Thai matter. Also , I'd be interested to find out if there was anywhere that the quote "attributed" to Dr. Wibulpolpraset (re. Western tourist hostages) was actually 'in print'.
The link below is to the W.H.O report of the "Commission on intellectual Property Rights".
