Sounds like owned by locals but managed by the Trump organisation, not actually owned by Donald and Co as elsewhere in the world. Be interesting to know where the £$£$ is coming from especially as Dubai has been getting a bad press over the last few years for being in general financial difficulties, all those incomplete buildings, Tigers never finished course, ex-pats coming home, alleged bailouts from Abu Dhabi, cranes on the skyline etc. Curious.
All the best.
