Your 4370. 
Minister has discussed this question with Netherlands Minister  and previously considered it when raised at Round Table Conference.
Dutch New Guinea has never been regarded by us as forming part of Indonesia as demonstrated by inclusion of Dutch New Guinea in area of South Pacific Commission.
Dutch trusteeship has always, in our view, been best solution. Any attempt to force the issue along lines United Kingdom propose 'for the present' might easily result in territory going completely outside any form of Dutch control.
For your information, before receipt of your 4370 Minister had already conveyed these views informally to Netherlands Minister.
Please pass confidentially to The Hague.
