Ethics - Most Strict Rules Apply

Not sure about the answer for this question:

If you live in a country with MS (More Strict) rules, and do business in a country with less strict (LS) rules, you should use/follow CFA rules. But what happens if the MS country tells you to follow the rules from where you do business? In this case you should also apply CFA Rules or LS with MS says to follow those?

Always follow the more strict rules. In this case follow CFA set of rules.
