Shock and awe! A loaded ashtray!
These Potentates also left behind an unpaid bill for "hundreds of thousands", (the suite was £8000+ a night for the Principal, there would be others for the retinue) apparently a normal thing at this level.
The last time this person stayed there it took 9 months to settle the bill.
On the subject of smoking, it's a fact that like all the other stuff which we the great unwashed have had give up or toe the line with like ecology, diet, etc. the nobs have completely ignored and sail along as they always have done in their gas guzzling Bentleys, homes that require the energy of a small town to heat, private yachts, aircraft etc. (all of which are at the disposal of our caring politicians for their hols)
The sort of Hotels and clubs frequented by our betters would not dream of telling their guests to put out their Cuban cigars...
My guess is that ashtrays full or otherwise are very low on the management's radar, apart that is from seeing that they are replaced with clean ones every time these folk leave their rooms.
