Sheikh Mujib’s pro-India policies antagonised many in politics and the military. The assassination of Mujib in 1975 led to the establishment of military regimes that sought to distance the country from India. Mujib’s death led to the establishment of diplomatic relations with Pakistan and other nations that had opposed the creation of Bangladesh, such as Saudi Arabia and the People’s Republic of China. Bangladesh was criticised for allowing Indian secessionist groups such as the United Liberation Front of Assam (ULFA) to operate from bases on its territory, and Bangladeshi intelligence agencies were suspected of maintaining links with Pakistan’s intelligence agencies. Bangladesh in turn alleged that India was supporting the Shanti Bahini insurgency in the Chittagong Hill Tracts. The two governments declined to renegotiate or renew the treaty when it approached expiry in 1997.
