Maybe there's more than one Chinese consortium in the world.
The Americans have made several bids, with proof of funds as the HDM suggest, and have been trying to get this over the line for ages.
The Americans seem brilliant, I'm really hoping that one goes through. Hopefully all this messing about by the Allams is just them squeezing as much money as possible out of it rather than deliberately putting the Americans of because they'd be good for us, but you wouldn't put it past the Allams would you...
