The Jinchon Sea is a marginal sea of the Eastern Cantalle Ocean. It is bound by western Ausiana with the basins of Siniapore, Tosichi, Emansi, Sanpia, and Gangkou surrounding it, with connections to the Lengshan Gulf and Mitali Sea. It is a region of tremendous economic and geostrategic importance, as nearly a third of global maritime trade is shared between it and the Sancheon Gulf areas. Huge oil and natural gas reserves are believed to lie beneath its seabed. It also contains lucrative fisheries, which are crucial for the food security of millions in Southwest Ausiana. Several contested territorial claims by nations has led to the ongoing Jinchon Sea crisis.
