"MBA degree from which these countries UK,Australia,Singapore,South Korea or Taiwan will have more value in Gulf countries and in the world?

Not sure. You're going to have to be more specific - but a UK degree, if it's from LBS or Said, will probably be more generally helpful wherever you go.

However, degrees from the country you're in can carry more weight in that country - whether that's from the connections that the school has or the connections you personally make while you're there, through internships, etc. Unfortunately, there are not a lot of great MBA programs in the gulf countries.

Which country are you looking at, specifically?

You might want to check out SP Jain. They have a campus in Dubai - and is now ranked in the FT Global rankings - not at the top, mind you, but the way this region is developing and the resources that are going into the program make this a pretty safe bet if you can afford it and want to stay in the Gulf.

I think it's probably safe to say that no matter where in the world you are: If whoever is hiring you values an MBA, they will also value a UK MBA (if it's from a good school).

And wow, Ralph, you sure have a lot of red hats!

Thanks ralph,Will it be good to do MBA from universities like Coventry(UK),Cardiff(UK),Bangor(UK) or S.P Jain(Dubai) to get good job in Gulf countries.My aim is to work in gulf countries after my MBA.And I want to purse MBA in marketing.

SP Jain is qualitatively better than those unaccredited UK universities.

Taiwan is not a country which belongs to PRC.

Nazme,

western education is good option - UK, USA etc when you planning to work in Middle East

and if you have worked in western countries before moving to middle east, it will have high value.

All the best
