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.

India’s Prime Minister Narendra Modi and Chinese President Xi Jinping met Wednesday on the sidelines of the BRICS summit in Russia, in their first bilateral meeting in five years. The meeting came days after the two giant neighbors announced a border accord aimed at ending a four-year-old standoff involving tens of thousands of their soldiers in the mountainous Ladakh region,

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.
