Foreign relations of India
India's relations with the world have evolved since the British Raj (1857–1947), when the British Empire monopolised external and defence relations. When India gained independence in 1947, few Indians had experience in making or conducting foreign policy. However, the country's oldest political party, the Indian National Congress, had established a small foreign department in 1925 to make overseas contacts and to publicise its independence struggle. From the late 1920s on, Jawaharlal Nehru, who had a long-standing interest in world affairs among independence leaders, formulated the Congress stance on international issues. As a member of the interim government in 1946, Nehru articulated India's approach to the world.
Treaty of Punakha
In August 1947, after India gained independence as a sovereign nation, the British presence upon which the Treaty of Punakha depended was no longer. Kingdoms such as Bhutan were given the option to remain independent, or join the Indian Union. Bhutan chose to remain independent and on 8 August 1949, Bhutan's independence was recognised by India. On 23 April 1948, Sonam Topgay Dorji, also of the Dorji family, headed the Bhutanese delegation to recently independent India, meeting Prime Minister Jawaharlal Nehru. Topgay and Nehru established Bhutan–India relations, prompted by a growing security concern over Communist China. Bilateral negotiations lasted through 8 August 1949, culminating in the Indo-Bhutan Treaty. Under this agreement, India returned the land around Deothang, subject of part of the 1865 Anglo-Bhutanese War.
