One year ago, no one would have expected that the world’s tallest tower known as Burj Dubai would rename itself into Burj Khalifa, in honor of Sheikh Khalifa Bin Zayed Al Nahyan, the ruler of Abu Dhabi. On Jan 4, 2010, Dubai announced the renaming decision for the 200-story, 828 meter tall skyscraper during its opening ceremony. Sources said that this action is to thank Abu Dhabi for the $10 billion lifeline which recently saved Dubai from financial crisis. The renaming decision is also intended to reflect the unity of the federation, according to Sheikh Ahmed bin Saeed al-Maktoum, chairman of Dubai’s Supreme Fiscal Committee
