In China most all business is conducted based on relationships. Their priority of decision makings seems to follow the Chi, Le, Fa path, which means relationships first, do the moral or right thing second, and Fa (French word related to law) or adhere to the law or contract as the third priority. That would mean if you got a signature on a contract, you didn't accomplish much if you didn't also develop a long term personal relationship.
