English was prevalently used as the language of choice in international politics and commerce. Foreign heads of state and diplomats from non-English speaking countries, such as the People's Republic of China, Turkey, Sangala, and the Islamic Republic of Kamistan generally spoke fluent English.

Background information and notesEdit
As an American production, English is the primary language used on 24. Non-American characters in the series who might be expected to speak a non-English language typically speak English, with only a few occasional exceptions. For example, Hector Salazar and Gael Ortega converse in subtitled Spanish during their introductory scene in "Day 3: 1:00pm-2:00pm," but use English almost exclusively in all scenes afterward. Another notable exception occurs in "Day 7: 11:00am-12:00pm," in which Sangalan officials speak unsubtitled French for several minutes. The prevalence of English in such situations is most likely for the benefit of 24's primarily English-speaking audience, as well as the fact that the actors are not necessarily versed in the same language that their characters are.
