China was also carrying out further construction in the Menchuma Valley, east of Jakarlung. Pollock said it, too, could be included in Bhutan's territorial concession.

Thimphu's potential concessions to Beijing in Jakarlung and Menchuma could greatly undermine Bhutan's sovereignty and territorial integrity, he said.
