DUBAI - Dubai has opened the world's tallest building as the emirate tries to re-establish some of the optimism it experienced prior to its financial crisis.
As he inaugurated the 828-metre high tower on Monday, Sheikh Mohammad bin Rashed al-Maktoum, the ruler of Dubai, renamed it Burj Khalifa in honour of Sheikh Khalifa bin Zayed al-Nahayan, the president of the United Arab Emirates.
Burj Khalifa, which took about 12,000 labourers to build, overtook its nearest rival - the Taipei 101 in Taiwan which rises to only 508 metres.
