In general, you want to study where you want to end up working. I don't think that either of these programs would give you much leverage in terms of landing jobs in anywhere else besides Malaysia. Nottingham's a UK school, and while it does have some alumni in the UK, you'd be up against some major visa challenges if you tried to go there for work.
If you wanted to stay in the region but had broader geographic career ambitions, a ranked MBA in Singapore might be a good option. Insead, in fact, matches up with your goals quite well: it's got a wide network in Europe and in the Middle East; the school even has campuses in both of these regions.
