Petronas Twin Tower Malaysia was The World Tallest Building from from 1998 ~ 2004 with 452m height. The world tallest building title was then taken by Taipei 101 with the height of 501m. Now from 2009, the title belongs to Burj Khalifa from United Arab Emirates with the height of 818m, almost double the size of Petronas Twin Tower. I wonder which country can beat such building.
