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.

Four years ago, several soldiers from both sides were killed in a bloody melee. Any thaw between the countries could have global implications.

Going forward China will work with India to implement these resolutions, Chinese foreign spokesperson Jian said refusing to provide details at a press briefing in Beijing.
