I don't necessarily mean marrying African women (tho' why not? historically colonists have always enthusiastically intermarried) but being out of China and working on labour-intensive projects like major infrastructure. Societies with lots of frustrated young men in them tend to go horribly wrong, Afghanistan is an example, in a society where there is a shortage of women anyway due to cultural reasons (e.g. healthcare), and successful men have 4 wives, and there is no social scene for teenagers and certainly no extramarital sex, what do the young men do? They run off into the mountains and it all goes a bit Lord of the Flies.
