The International Chamber of Commerce (founded 1920) acts as the voice of the business community in the international field and runs a court of arbitration for settling commercial disputes. National chambers of commerce exist in most industrialized, free-enterprise countries. The first to use the name was founded in Paris in 1601; the first U.S. chamber of commerce was that of the state of New York, founded in 1768.
