From Portuguese China, perhaps from Hindi ??? (cīn) and ultimately from Sanskrit ??? (cīna, “the Chinese; China”) of uncertain etymology. It is usually thought to be derived from 秦 (qín, “Qin”), Middle Chinese: 秦(MC d?zi?n), Old Chinese: 秦 (OC *zin), the westernmost ancient Chinese state, but other theories have been proposed, including derivation from 晉／晋 (jìn, “Jin”), Middle Chinese: 晉 (MC t?si?n^H), Old Chinese: 晉 (OC*?sins), 荊／荆 (jīng, “Jing”), or the Zina of 夜郎 (Yèláng, “Yelang”)
