for holders only very simple reaserch, page-50

To get $6.5B loan, you need:
1) Assets as collateral - do you think he has enough assets (need several billions of assets)
2) Syndicate of banks - probably 10 different banks to share risk, which bank?
3) Advisers like Macquarie and Goldman Sachs to work out the numbers; does this project profitable enough to repay loan?

IMHO none of above. Besides you also need other projects to develop at the same time to use this infrastructure. CITIC Sino probably had no knowledge of this.

Just IMHO.
