Global or International, what's the diff?

Just because this question came up a couple times recently, let me provide some definitions:

International business: A group of sister corporations that operate independently around the world. Each unit usually addresses the local market as best they see fit. How about Ford, Pizza Hut, Masterfoods.

Global business: a group of company divisions that work together as a single business entity. Think IBM, Samsung, Sony.

We are seeing our clients act more and more like Global businesses, which creates new challenges and makes doing business that much more complex.
