India and China have reached an agreement on military disengagement along their disputed border, New Delhi said, a step toward reducing frictions between the nuclear-armed neighbors that comes as both countries’ leaders arrive in Russia for a summit.

Indian Foreign Minister Subrahmanyam Jaishankar on Monday said the regional rivals had reached an agreement on patrolling the border, signalling an end to the military standoff, although China did not immediately confirm the pact.

Tensions between the Asian powers had flared in recent years following a border clash that left at least two dozen soldiers dead.
