The Chinese referred to outsiders/foreigners as barbarians.

This would be false as he said in  matthew 22: 21 jesus said "render to  caesar the  things that are  caesar's; and to god  the  things that are god's." romans 13: 1 "let every person be in subjection to  the  governing authorities. for there is no authority except from god and those which exist are established by god."
