Bhutan

Bhutan is one of the most unknown countries in Asia, thanks in part to its many unique features, such as that you can only fly there with local airlines, from very few airports in the world, because it has only one international airport with very complex access , as well as, that it is considered one of the least developed countries in the world, to the point that it is considered one of the few that absorbs more carbon dioxide than it emits, thanks in part to its vast nature and mountainous terrain that has spectacular valleys  It is a country without access to the sea, hidden in the depths of the eastern Himalayas, which borders India and China, although the latter do not have a great relationship with them at present, so India is its great commercial partner and the only one with which it has open land borders.
