International congresses are congresses that take place according to a previously established schedule (annual, bi-annual…), generally gathering large numbers of participants interested in a specific field. International congresses are held in various countries, and cities. Countries wishing to host these events apply by offering their prime congress facilities, promoting particular destinations, and lobbying for their selection. This term should not be confused with congresses with international participation, because a congress involving international participation refers to the participation of delegates from various countries and not to the fact that it takes place in different countries. Furthermore, international congresses are recognized and renowned worldwide, while congresses with international participation generally pertain to a single country.
