Pax Sinica (Latin for "Chinese peace"; simplified Chinese: 中华治世; traditional Chinese: 中華治世; pinyin: Zhōnghuá Zhìshì) is a historiographical term referring to periods of peace in East Asia,[1] Northeast Asia,[2] Southeast Asia,[1] and Central Asia[3] led by China. A study on the Sinocentric world system says the multiple periods of Pax Sinica, when taken together, amounted to a length of approximately two thousand years.[4]
