I would recommend Singapore--a lot to see in a small space (also some side trips to Indonesia and KL would be great). Korea is also very efficient, high quality education, and the country provides some wondefully contrating environments. China is not very efficient, poor quality and only good if you have extra resources to spend. In sum, nothing special. I'm doing well: its just confirmed that I'll be in Australia and NZ for a few months in 2014.
