evidence: The book of the 1986 British expedition gives the mountain’s height as 7,550 metres (24,770 ft) and states that Gangkhar Puensum is completely inside Bhutan, whereas the nearby Kula Kangri is completely inside Tibet. Kula Kangri, 7,554 metres, is a separate mountain 30 km (20 mi) to the northeast which was first climbed in 1986. It is variously mapped and described as being in Tibet or Bhutan. [...] In 1998 a Japanese expedition secured permission from the Chinese Mountaineering Association to climb the mountain, but permission was withdrawn because of a political issue with Bhutan. Instead, in 1999, the team set off from Tibet and successfully climbed the 7,535-metre subsidiary peak Liankang Kangri (also known as Gangkhar Puensum North).
