The new Super Tower in Bangkok will be the tallest building in South-east Asia in 2019, but it has some serious competition in the rest of Asia.
Here are the contenders for the tallest building in Asia, including some still under construction:
Where: Dubai How high: 828m Completed: 2010
The Burj is now the undisputed tallest building in the world, but the planned 1-kilometre-tall Kingdom Tower in Saudi Arabia, which is under construction, snaps at its heels.

The 660m Ping An Finance Center in the southern city of Shenzhen will be China's tallest building when completed in 2016.

Until Ping An is complete, the Shanghai Tower will momentarily lay claim to the title of the tallest building in China. The new tower integrates with two nearby skyscrapers: Jin Mao Tower and Shanghai World Financial Center (currently China's tallest).

At double the height of Thailand's current tallest building - Baiyoke Tower II (328m) - the 125-storey tower will include a six-star hotel, and an observation deck.

It was to be South-east Asia's tallest tower, but projected to come a year after (Bangkok's) Super Tower. KL118 was originally named the Warisan Merdeka, but it may be late to the party.
The condominium and hotel complex in Kuala Lumpur's colonial district will be 118 storeys high.

The skyscraper in Shanghai's Pudong district was meant to top Taipei 101, but a height limit was imposed. Its highest occupied floor does exceed the Burj Khalifa's at 474m.

Hong Kong's tallest building not only houses offices, it has a facade that is the canvas for the largest light and sound show on a single building in the world, according to Hong Kong's Tourism Board.

The complex in Malaysia's capital was the tallest building in the world until overtaken by Taipei 101 in 2004 (and so on). It still holds the record for the tallest twin towers in the world.
