<P> The boundary between Europe and Asia is purely conventional, and several conventions remained in use well into the 20th century . However, the now - prevalent convention, used for the purposes of this list, follows the Caucasus northern chain, the Ural River and the Ural Mountains . It has been in use by some cartographers since about 1850 . This convention results in several countries finding themselves almost entirely in "Asia", with a few small enclaves or districts technically in "Europe". Notwithstanding these anomalies, this list of transcontinental or intercontinental states respects the convention that Europe and Asia are full continents rather than subcontinents or component landmasses of the larger Eurasian continent . </P> <P> Listed further below, separately, are countries with distant non-contiguous parts (overseas territories) on separate continents . </P> <P> The modern convention for the land boundary between Asia and Africa runs along the Isthmus of Suez and the Suez Canal in Egypt . The border continues through the Gulf of Suez, Red Sea and Gulf of Aden . In antiquity, Egypt had been considered part of Asia, with the Catabathmus Magnus escarpment taken as the boundary with Africa (Libya). </P> <Ul> <Li> Two of 27 governorates of Egypt lie entirely on the Asian Sinai Peninsula and two are transcontinental: Ismailia Governorate is nearly equally divided by the Suez Canal, and Suez Governorate, which is coterminous with the "transcontinental city" of Suez, has a small portion east of the Canal . </Li> </Ul>
