AUH has provided billions for Dubai, that's a fact!
Like I said, Dubai is like a big holding of companies incl. EK and Emaar.
So if EK will ever get into trouble, Dubai would back them as they do presently with others and ask AUH for more dough. Anybody really knows how much of EK already belongs to AUH? AUH has definitely asked Dubai for guarantees for the bail out! You can always ask PwC.
Btw HSBC, Standard Chartered and RBS are presently selling sukuk bonds for Emaar...and will probably find enough wannabe crisis profiteers.
You and me won't invest in Dubai but enough banks and investors will do...and guess who is paying the bill at the end?
