Dubai Skyscraper’s New Name Shows Shifting Fortunes

Dubai renamed the world’s tallest building in honor of Abu Dhabi’s leader less than a month after receiving a $10 billion lifeline from the neighboring emirate that defused a financial crisis.

The 200-story Burj Khalifa, or Khalifa Tower, was known until yesterday as Burj Dubai. Sheikh Khalifa Bin Zayed Al Nahyan, who has ruled Abu Dhabi since 2004, is also president of the United Arab Emirates.
