It is fairly evenly sandwiched between the sovereign territory of two nations: first, the People's Republic of China on the north and northwest. There are approximately 477 kilometres of border with that nation's Tibet Autonomous Region. The second nation is the Republic of India on the south, southwest, and east; there are approximately 659 kilometres with the states of Arunachal Pradesh, Assam, West Bengal, and Sikkim, in clockwise order from the kingdom. Bhutan's total borders amount to 1,139 kilometres.
