I used to teach English to non-native speakers. All of them wanted to learn English with an American accent. I think they are actually doing themselves a disservice because they fail to understand the subtle differences of class status an accent signals. A more British inflected accent is an easy way to signal higher education and status to an American. They go a bit gaga for British accents. It's also easier to fake a British accent.
The weird thing in the Middle East is (outside of Saudi) most of the formal instruction was in British English, but everyone watched US tv, and the demand was generally for a American English (even after 9/11 and the unwelcoming US immigration policy).
Same thing in China and Thailand; I don't know about other countries.
