|Component with Country Specific sub pages|
This can be controlled at the primary permission list level of a user id. The countries that a certain primary permission list has access to, can be setup in Setup HRMS > Security > Component and Page Security > Setup Global Security > Setup Global Security.
In the above navigation, you can enter the countries that a primary permission list has access to and once the primary permission list is attached to a userid, that user will only be able to view sub pages from the configured countries.
It is as simple as that!
