China is the least flat country in the world, with an altitude range of 9,002 m (29,534 ft) from the Turpan depression at 154 m (505 ft) below sea level to the peak of Mt Everest at 8,848 m (29,028 ft) above sea level.
Mt Everest is on the border with Nepal and Tibet, and as Tibet is considered part of China then China qualifies.
