Thimphu

Thimphu and Delhi share a close relationship and India has been offering hundreds of millions of dollars of economic and military aid to Thimphu.

Bhutan and China claim the region and India supports Thimphu's position.

India has its own reasons to back Thimphu.

While many Bhutanese were surprised by the reaction to Mr Tshering's comments in the Indian media, the view from China is that Thimphu will struggle to reach a deal without Delhi's backing.

Some of them say Thimphu is not pressing hard enough over its claims on Doklam.
