MGM Mirage insists it will meet its financial obligations to complete the $9 billion CityCenter project on the Las Vegas Strip. The company responded today to a lawsuit filed over the weekend by Dubai World, its partner in the CityCenter development. In the suit, Dubai World accused MGM Mirage of mismanaging the CityCenter project and questioned its overall viability. But in a statement, MGM Mirage called the suit "completely without merit," and added that it wants to work with Dubai "to resolve any outsanding issues and complete this landmark project." CityCenter includes six high-rise condo towers with a casino, hotels, condos and retail and restaurant space. It is scheduled to open in phases starting later this year.
