Vaifanua County is a county in the Eastern District in American Samoa.[1][2][3]
Vaifanua and Sua counties are both ruled by the Le’iato family, one branch of which lives in Fagaitua, the principal place of Sua County. Another lives in Sa'ilele near Aoa, which is the principal place of Vaifanua County. These two Le’iato family branches, along with two orators from each, conduct the affairs of government for the two counties.
