A couple of Chinese companies have signed onto a joint-venture agreement to construct the world’s tallest twin towers in Cambodia’s capital of Phnom Penh. Once complete, the towers will include 133 floors and reach 560 meters in height, 108 meters taller than the current record-holder, Kuala Lumpur’s Petronas Towers. They would also be 372 meters taller than the city’s tallest building at the moment.
