In the last half of the 7th century, when Shiragi (Silla) unified the Korean Peninsula, countries in the Korean Peninsula used to be referred to as "Shoban" became in fact the one country, so that the term Shoban was sometimes used in the sense of Shiragi.
また、7世紀後半に新羅が朝鮮半島を統一すると、対象国が事実上同国のみとなってしまったために新羅を指して蕃国と呼ぶ例も現れる。
