The Saudi prince currently developing the world’s tallest tower has invited the Dubai developer¬†Emaar to help develop an even higher building – a mile high – in one of the world’s largest cities.

Prince Al Waleed bin Talal, one of the world’s richest men, has invited the Emaar chairman Mohammed Alabbar to team up with his property development company Kingdom Holding to develop the tower, according to reports.

The prince said he was looking at various locations.

“I am now inviting the major cities of the world like Shanghai, Moscow, New York, London and regional cities in the Middle East to come and give their offers,” Prince Al Waleed told Reuters, adding that interested countries would have to offer attractive financing terms or tax breaks.

He did not say how much the project would cost or how he planned to finance it.

Kingdom Holding is currently developing the Kindgom Tower in Jeddah that is set to overtake the 828-metre tall Burj Khalifa in Dubai when it is completed in 2017. More info
