There are only 2 disputed areas raised in 24 boundary talks since 1984 agreed to by both sides with signed minutes (269 sq km in West & 495 sq km in North-Central Bhutan)
The Chinese never brought this up in the boundary talks.
So there is no dispute in Eastern Bhutan.
This Eastern sector is very much Bhutanese with a large Bhutanese population and traditional Dzongs ( Medieval Fortresses) & two Bhutanese districts since time immemorial.
Such claims undermine the boundary talks and wild claims on either side by officials will only exacerbate issues as Bhutan too can lay claims far north.
This is of course keeping India in the picture in terms of its strategic interests in the area.
