MGM Mirage follows Las Vegas-based rivals Wynn Resorts Ltd. and Las Vegas Sands Corp. in seeking to raise funds from selling stakes in their operations in Macau, where gambling revenue is recovering. Murren's reiteration of plans to sell shares comes a day after a report that China tightened curbs on citizens' travel to Macau, the only Chinese region where casinos are legal. "In the short term, too many Macau plays may not be too good because of the unclear picture" surrounding travel policy, John Koh, who helps manage $1.1 billion at MEAG Hong Kong Ltd., said in a phone interview today.
