Tongshanjiabu, Unclimbed mountain on the Bhutan-China border

Tongshanjiabu, also called Gyalbu Kangri, is a 7,207-metre peak in the central Himalayas, 12 km northwest of Kangphu Kang. It lies on the Bhutan–Tibet border. SRTM data give 7,105 m, so its rank among the 7,200ers is uncertain. The name appears on a Japanese Alpine News map of May 2003.

The mountain has been caught in territorial disputes since 1959, when China published maps claiming portions of Bhutanese land. This border uncertainty has continued to shape access and activity in the surrounding area.

The name Tongshanjiabu appears on a map published in Japanese Alpine News in May 2003, which is how the peak became known outside the region. The label "Teri Kang" sometimes used for the area belongs to a nearby subsidiary top, not to the 7,207 m summit itself.

The mountain sits in a sensitive border zone that requires permits and coordination with both Bhutanese and Chinese authorities for any approach. Its remote position and ongoing border tensions make access effectively closed to ordinary visitors.

The name Tongshanjiabu appears on a map published in Japanese Alpine News in May 2003, which is how the peak became known to outside cartography. Russian sources give the Chinese form 同山加布峰 and place it about 12 km northwest of Kangphu Kang.
