Senior Dubai officials have said the changing of the name of the world's tallest tower to Burj Khalifa reflected the unity of the UAE federation.
Dubai renamed the 200-storey building, previous known as the Burj Dubai, in honour of the ruler of Abu Dhabi - an announcement made at a spectacular opening ceremony on Monday night.
“Sheikh Khalifa is one of the UAE’s symbols,” said Sheikh Ahmed bin Saeed al-Maktoum, chairman of Dubai’s Supreme Fiscal Committee and an uncle of Dubai’s ruler, Sheikh Mohammed bin Rashid Al Maktoum.
