Indian Foreign Secretary Vikram Misri announced on October 21 that India and China had reached “an agreement… on patrolling arrangements along the Line of Actual Control… leading to disengagement and a resolution of the issues that had arisen” following Chinese transgressions “in these areas in 2020”. The question that remains to be clarified is whether “disengagement” will cover all extant areas of dispute where patrolling has been blocked on both sides, including the so-called “legacy disputes” in eastern Ladakh at Demchok and Depsang or only those areas that came into contention in 2020.
The United States has expressed approval over the easing of tensions along the India-China border, following the recent disengagement of troops from both countries along the Line of Actual Control (LAC).
Matthew Miller, the spokesperson for the US said “We are closely following the developments and we understand that both countries have taken initial steps to withdraw troops from the friction points along the LAC. We welcome any reduction in tensions along the border,” Miller said during a press briefing.
"We have talked to our Indian partners and taken a brief on it, but we did not play any role in this resolution," he added.
The agreement, announced earlier this week, has enabled both sides to begin troop withdrawals from key friction points in eastern Ladakh, including the Depsang Plains and Demchok. The process, which follows over four years of military standoff, is expected to be completed by the end of October.
When Prime Minister Narendra Modi met Chinese President Xi Jinping in Russia for the Brics summit, Jaishankar noted, they agreed that foreign ministers and National Security Advisors from both nations would hold discussions on further steps.
