For nearly three weeks, Chinese and Indian border troops have confronted each other close to a valley controlled by China that separates India from Bhutan - a close Indian ally - and gives China access to the so-called Chicken's Neck, a thin strip of land that connects India to its remote northeastern regions.

It has escalated tensions between the neighboring giants, who share a 3,500-kilometer (2,175-mile) frontier, large parts of which are disputed. Beijing alleges Indian troops crossed into a region known in China as Donglang, called Doklam in India, early in June and obstructed work on a road on the Himalayan plateau.

Chinese officials say the Indian side's actions infringe upon an 1890 border agreement between Britain and China that previous Indian governments pledged to uphold.
