Dubai’s investment arm was given permission to increase its ownership of MGM Mirage last week, but one of its executives said that won’t happen until market conditions warrant such a move. The Nevada Gaming Commission found Dubai World a suitable business and joint venture partner for MGM Mirage. Last year, Dubai World invested roughly USD 6 billion to acquire 9.4 % of MGM Mirage’s outstanding shares and a 50 % interest in the USD 9.1 billion CityCenter development, which is now under construction.
