Rohingya in Myanmar) fled the country on foot or by boat (chiefly to Bangladesh) creating a major humanitarian crisis. The governments of Myanmar and Bangladesh signed a memorandum of understanding on 23 November 2017 regarding the repatriation of Rohingya refugees to Rakhine State. However, till the end of the decade over 740,000 refugees remained in Bangladesh creating pressure on the country's economy and infrastructure. The 2018 General elections brought another landslide victory for the Awami League led by Sheikh Hasina. While the opposition was already weak due to key leaders being in either jail or exile, the elections were further marred by violence and claims of vote rigging. However, this gave the Awami League Government stability and opportunity to complete key infrastructure projects for the country including the Padma Bridge and the Dhaka Metro Rail. Chittagong Hill Tracts conflict The Chittagong Hill Tracts is the south-eastern mountainous frontier of Bangladesh with Myanmar and Northeast India. The area enjoyed autonomy under British Bengal. Its autonomous status was revoked by Pakistan, which built the controversial Kaptai Dam that displaced the area's indigenous people. When Bangladesh became independent, the government of Sheikh Mujibur Rahman adopted a Bengali nationalist constitution, which denied recognition of the country's ethnic minorities. Manabendra Narayan Larma, a member of parliament form the hill tracts, called for constitutional recognition of the indigenous people of the area. He gave a notable speech at the Constituent Assembly of Bangladesh demanding the use of "Bangladeshi" as the country's nationality definition, instead of Bengali. During the 1970s and '80s, there were attempts by the government to settle with the Bengali people. These attempts were resisted by the hill tribes, who, with the latent support of neighbouring India, formed a guerrilla force called Shanti Bahini. As a result of the tribal resistance movement, successive governments turned the Hill Tracts into a militarised zone. Following years of unrest, the Chittagong Hill Tracts Peace Accord was formed between the government of Bangladesh and the tribal leaders which granted a limited level of autonomy to the elected council of the three hill districts.
