Dubai plans to build a tower that will stand higher than its Burj Khalifa, currently the world's tallest skyscraper, property developer Emaar said on Sunday (April 10).
The exact height has not been released, but it is expected to be completed before 2020, in time for the World Expo trade fair, expected to run from Oct 20, 2020, to April 10, 2021. Dubai will be the first city in the Middle East to host this event.
The tower will have observation decks, restaurants and a boutique hotel.
Here is a guide to five of the tallest buildings in Asia, for travellers to explore.
