On 29 June 2017, Bhutan protested the Chinese construction of a road in the disputed territory. The Bhutanese border was put on high alert and border security was tightened as a result of the growing tensions. On the same day, China released a map depicting Doklam as part of China, claiming, via the map, that all territory up to Gipmochi belonged to China by the 1890 Britain-China treaty.
