Sinocentrism refers to a worldview that China is the cultural, political, or economic center of the world. Sinocentrism was a core concept in various Chinese dynasties. The Chinese considered themselves to be "all-under-Heaven", ruled by the emperor, known as Son of Heaven. Those that lived outside of the Huaxia were regarded as "barbarians". In addition, states outside of China, such as Vietnam, Japan or Korea, were considered to be vassals of China.
