It is the case, for instance, of anti-circumvention provisions. The definition of “circumvention” is so vague that it is almost impossible to change in any way the forestry policy of a province. It even requires the province to ask the permission of the Americans to adopt a change.
It would be very easy for the Americans to give the assurance that a change towards free markets will never be considered as circumvention. It would be reassuring for everyone.
