Generally close ally, but occasional strains: border demarcation issues, Bhutanese refugee (Lhotshampa) situation, trade imbalances.
Disputed border (especially Doklam plateau); China's growing regional influence and infrastructure development near borders pose strategic concerns.
Bhutan pursues diplomacy (balancing India and China), sustainable development (GNH), and internal reforms to maintain stability and sovereignty.
Bhutan maintains peaceful relations with all nations; "enemies" is not an official concept. The above are risk factors, not active hostilities.
