States maintain diplomatic relations and work through some elements of international law, such as:
International treaties
Embassies and consulates
International organisations

4. International treaties
Are agreements between states, which can be worldwide (Universal Declaration of Human Rights, 1948) or restricted to some states (Concordato con la Santa Sede 1979).

5. EMBASSIES AND CONSULATES
States usually have embassies and consulates in foreign countries in order to provide services to their nationals and to keep diplomatic contacts with that state.
An embassy is the larger representation, but a consulate is only a smaller version of the embassy. Consulates in a sense can be called junior embassies.
