Bangladesh's most politically important bilateral relationship is with neighbouring India. In 2015, major Indian newspapers called Bangladesh a "trusted friend". Bangladesh and India are South Asia's largest trading partners. The countries are collaborating in regional economic and infrastructure projects, such as a regional motor-vehicle agreement in eastern South Asia and a coastal shipping agreement in the Bay of Bengal. Indo-Bangladesh relations often emphasise a shared cultural heritage, democratic values and a history of support for Bangladeshi independence. Despite political goodwill, border killings of Bangladeshi civilians and the lack of a comprehensive water-sharing agreement for 54 trans-boundary rivers are major issues. In 2017, India joined Russia and China in refusing to condemn Myanmar's atrocities against the Rohingya, which contradicted with Bangladesh's demand for recognising Rohingya human rights. However, the Indian air force delivered aid shipments for Rohingya refugees in Bangladesh. The crackdown against cattle smuggling in India has also affected Bangladesh. The Bangladeshi beef and leather industries have seen increased prices due to the Indian BJP government's campaign against the export of beef and cattle skin.
