evidence: The agreement led to another duration of relative peace until on 16 June 2017 Chinese troops with construction vehicles and road-building equipment under the Belt and Road initiative began extending an existing road southward in Doklam, a territory which is claimed by both China as well as India's ally Bhutan. On June 18, 2017, around 270 Indian troops, with weapons and two bulldozers, entered Doklam to stop the Chinese troops from constructing the road assuming that the 2007 India-Bhutan Friendship Treaty was a enough of a reason for preventive action, to say nothing of their issues relating to national interests. Among other charges, China accused India of illegal intrusion into its territory, across what is called the mutually agreed China-India boundary, and violation of its territorial sovereignty and UN Charter. India accused China of changing the status quo in violation of a 2012 understanding between the two governments regarding the tri-junction boundary points and causing "security concerns", which were widely understood as at its concerns with the strategic Siliguri Corridor. The main reason for Delhi’s intervention was its fear that, if China controlled the Siliguri corridor "chicken’s neck", a thin strip of land just south of Doklam, it would cut off India from its northeastern states, including Arunachal Pradesh – over which China claims sovereignty.
