Question

Sikkim is called the only brother of seven sister states why

Answer 1

As we know North East India is known as Land of Seven Sisters because they are interdependent on each other. And the neighbor is Sikkim so it is referred as only brother of seven sisters states.

Answer 2

Sikkim is a landlocked state which shares borders with Nepal, China, Bhutan and West Bengal. Unlike the other seven states in the north-east, which share a contiguous border, Sikkim is some distance away. Therefore, it is called the only brother among seven sisters. The state is a late entrant to the north-eastern council.
