What is the deal with Chinese sheetrock?

Can someone please inform me about what is going on with Chinese drywall. I found out yesterday from someone who recently moved from Florida that drywall in Florida was corroding copper pipes and wiring in houses. So I decided to Google Chinese drywall and an unbelieveable amount of newspaper articles came up about the issue. Is this a real concern or is it something that was caused by all of the hurricanes the past couple of years? Is this the new black mold?

I am really interested in finding out more about this issue. How do you go back and find out if your builder purchased his drywall from a state that imported the material? Is it only in Florida and other coastal areas where it issues are popping up? If anyone can break it down for me I would like to hear your opinion on the issue.

I imagine this will be a hot topic for some time to come between the insuarance companies, builders, suppliers, Realtors, homeowners, and the government.
