Burj Khalifa to remain world's tallest 'for years'
The Burj Khalifa is set to remain the world's tallest building for years to come despite a skyscraper building boom in China, according to building data firm Emporis.
Dubai opened the world's tallest skyscraper Monday, and in a surprise move renamed the gleaming glass-and-metal tower Burj Khalifa in a nod to the leader of neighboring Abu Dhabi -- the oil-rich sheikdom which came to its rescue during the financial meltdown.
