The basic framework of India-Bhutan bilateral relations was the Treaty of Friendship and Cooperation signed in 1949 between the two countries. It called for peace between the two nations and non-interference in each other's internal affairs. The Treaty was revised in 2007.

The diplomatic relations were established in 1968 with the establishment of a special office of India in Thimphu. There are a number of institutional and diplomatic mechanisms between India and Bhutan in areas such as security, border management, trade, transit, economic, hydro-power, development cooperation, water resources etc.

Bhutan shares its border with four Indian states - Assam, Arunachal Pradesh, West Bengal and Sikkim with a length of 699 km and serves as a buffer between India and China.

The trade between the two countries is governed by the India-Bhutan Trade and Transit Agreement of 1972. India is Bhutan's largest trading partner. India has constructed three Hydroelectric Projects (HEPs) in Bhutan: Chukha HEP, Kurichhu HEP, and Tala HEP, operational and exporting surplus power to India.
