The two countries have agreed to a speedy disengagement on the Doklam plateau in Bhutan, ending a military standoff lasting more than two months.
China's Ministry of Foreign Affairs said Beijing would continue to patrol the region.

India ignored repeated baiting and aggressive rhetoric by China to insist it would seek diplomatic channels to resolve the tension.
India's serious security concern over the road stems from the access it opens up to the narrow strip of land called the "Chicken's Neck" that links mainland India to its north eastern states.
