Vertaling van "forme de collaboration du gouvernement sri-lankais sera absolument impossible " (Frans → Engels) :

En fin de compte, nous arriverons peut-être au point où il sera évident que l'obtention de n'importe quelle forme de collaboration du gouvernement sri-lankais sera absolument impossible.
Ultimately we may reach a point where it becomes clear that it's going to be absolutely impossible to obtain any kind of cooperation and collaboration from the Sri Lankan government, and at that time we and other organizations might say to UN member states, you have to move forward with it anyway.

Cela constituerait en soi un obstacle considérable à une enquête internationale efficace, parce que ce sera difficile, sans la collaboration du gouvernement sri-lankais.
That in itself would obviously be one very significant obstacle to carrying out an effective international investigation, because without the cooperation and collaboration of the Sri Lankan government, it will be difficult.
