President George W. Bush welcomed Dubai's ruler to his presidential retreat on Sunday, returning the favor for the opulent hospitality he received in the United Arab Emirates this year. At Camp David in rustic Maryland, Bush met with Sheik Mohammed bin Rashid al-Maktoum, the UAE's prime minister and ruler of Dubai. "You're looking good," Bush told al-Maktoum after the sheik arrived by helicopter. Both leaders were dressed casually and engaged in small talk before driving out of sight on a golf cart. Al-Maktoum's overnight stay at the presidential compound follows a visit to Camp David in late June by Sheik Mohammed bin Zayed Al Nahyan, the crown prince of Abu Dhabi, another in the UAE's string of seven semiautonomous emirates.
