That makes sense. I'm completely clueless on what Chinese bankruptcy laws are there, but here in the states we do have restructuring bankruptcy laws. Sears, K-Mart and others have used them for years. You are able to stave off your current creditors, sell off some assets to gain some capital and then try to build your way back out of it all.
I'm only guessing that Evergrande is doing something similar: writing off their current and soon-due debt and restructuring to where they'll be able to stay afloat long enough to recover and be able to pay off the distant future debts they have.
I am guessing though.
