Yeah, It's called Morals and Ethics!
This probably more than any other factor has lead to the West becoming basically the best places t live and work.
Unfortunately for a significant part of the World they either are meaningless or mean something completely different.
Therefore Westerners who deal with those other cultures are no expecting the unethical and immoral behavior of the individuals and get taken advantage of.

Think "Free " Trade with China. To the Chinese that mans they should have unfettered access to sell goods and Buy assets in Canada and maybe through in Citizenship.
I'm pretty sure they have no plans to allow the same!
