International community=international society???

Some scholars say international society means the same as international community, and so both serve as the English equivalent for the Chinese expression "guoji shehui" (literally "international" + "society").
But as I understand "international community" (the Chinese equivalent is "guoji shehui") is used withing the UN context; while "International society" is used in the context of international politics. But we can find many instances to prove that "international society" is often used with "psychology", reading "international society of psychology" and many similar organizations.
So I would like to know the exact definition of "international society" in political science.
