A diplomat is a person who works for a public institution whose purpose is to communicate
with other countries, promote cooperation with those countries, help people who are in a foreign country, etc.
A diplomat can work in his home country (for the Ministry of Foreign Affairs or a similar institution)
or in a foreign country (at a foreign mission: an embassy or a consulate). Diplomats who work
abroad include ambassadors and consuls.
