Questions on CORPs (White Giant)

If there if 2 corps in a country, like one produces gold and the other produces jewlry. Will the jewlry corp buy the gold it needs automaticly from the gold corp? Or do you have to set it up where the gold corp sells gold to the jewlry corp?

You have to set it up

Set up a contract between your two corporations. Make sure you accept the contract offer after making it.

I know its not what you asked, but I just wanted to let you know that if you're trying to make money you should trade on the free market. Make sure to buy quality 190 supplies.
