Bangladesh–India relations

Bangladesh–India relations are the bilateral relations between the People's Republic of Bangladesh and the Republic of India, both of which are South Asian neighbours. Diplomatic relations between the two countries formally began in 1971 with India's recognition of an independent Bangladesh (which was formerly known as East Pakistan) following India helping Bangladesh secure its independence during the Bangladesh Liberation War against Pakistan. On 6 December, Bangladesh and India celebrate Friendship Day commemorating India's recognition of Bangladesh and the continued friendship between the two countries.

Although some disputes remain unresolved, the relations between the two countries have been characterised as friendly. The historic land boundary agreement was signed on 6 June 2015 which settled decades-old border disputes, while negotiations are still ongoing over the sharing of water of the transboundary rivers. In recent years, Bangladesh has seen rising anti-India sentiments among its citizens due to the Indian government's perceived anti-Muslim and anti-Bangladeshi activities like India's interference in Bangladeshi politics, killings of Bangladeshis by Indian BSF, Citizenship Amendment Act, rise of Hindutva in India as well as India's reluctance in solving the water disputes in common rivers with Bangladesh. In 2019, several Bangladeshi ministers cancelled their scheduled state visits to India as a response to India's Citizenship Amendment Bill. In 2021, massive protests in Bangladesh against the state visit by Indian PM Narendra Modi to the country led to the deaths of at least 14 people.

Bangladesh and India are common members of SAARC, BIMSTEC, IORA and the Commonwealth. The two countries share many cultural ties. In particular, Bangladesh and the east Indian state of West Bengal are Bengali-speaking. In 1971, the Bangladesh Liberation War broke out between East Pakistan and West Pakistan; India intervened in December 1971 in support of East Pakistan and helped secure its independence from Pakistan as the country of Bangladesh. Since the visit of Indian Prime Minister Narendra Modi to Bangladesh in 2015 and round back visit of Bangladeshi Prime Minister Sheikh Hasina to India in 2017, the notable developments that have taken places include resolution of long-pending land and maritime boundaries asserting the issue of enclaves, conclusion of over ninety instruments comprising in the hi-tech areas, i.e., electronics, cyber-security, space, information technology, and civil nuclear energy and observed increase in bilateral trade from US$9 billion to US$10.46 billion in the fiscal year (FY) 2018–19, preceded by US$7 billion to US$9 billion in FY 2017–18, an increase of 28.5 percent.

The Bangladesh government is set to initiate three significant infrastructure projects with the backing of India's financial assistance. These projects encompass a power plant and railway links among other crucial developments.
