I have not worked in those 2 countries, but I do hear that folks in Qatar make up to 4,000 dollars a month with a master's. As for U.A.E. because of Dubai there are too many expats there and there are many scams. U.A.E. doesn't even bother to advertise their jobs because so many people want to go there. You have to go there yourself and look in the job ads. This is what a former colleague of mine from Saudi Arabia told me. I do know that in Kuwait a guy with a PH.D was making 5,000 dollars a month, on top of that students would offer to pay him 1,000 dollars just to pass them so they can go to a Western University and collect the 2,000 dollar pensions that the government gives to their better students. I would not take bribes nor am I advocating something like this but I do know that the median salary in the middle east is much higher than that of China. Just not a lot of things to spend money on like in Japan or the West.
