Ambassador
We call a representative to a foreign country an ambassador.
they call him the emperor
It depends on whether you live there or not. If you do not live there, it is a foreign country. If you live there, it is not a foreign country. Instead, it is called a mother country. ex)A person who lives in America would call Norway a foreign country because he or she does not live there. In contrast, a person who lives in Norway would call Norway his or her mother country because he or she lives there.
The person that speaks for you in a foreign country is an Interpreter, but depending on the location they may say the name in that given language.
