£75m offices and hotel 'boost city'
The 185-bedroom Radisson Park Inn is part of a regeneration scheme in the city centre.
Mr Salmond said: "The hotel has not only created 50 new jobs but will be a major contributor to the local economy as part of the overall 75m iQ development project.
"This opening is a clear demonstration that, in spite of very challenging times facing the sector, Scotland's tourism businesses continue to play an important role in achieving sustainable economic development."
A spokesman for the developers explained: "The hotel is part of the 75m iQ development project by the Edinburgh-based Hazledene Group, owned by Aberdonian businessman Mark Shaw. Hazledene has retained ownership of the hotel but it will be run by Rezidor."
