This came seven years after the previous government attempted and failed to push through the same reforms and 16 years after the sector was first opened to foreign investors up to 26% under the first BJP-led NDA Government under Atal Bihari Vajpayee's administration.[37] The second BJP-led NDA Government also opened up the coal industry through the passing of the Coal Mines (Special Provisions) Bill of 2015. It effectively ended the Indian central government's monopoly over the mining of coal, which existed since nationalization in 1973 through socialist controls. It has opened up the path for private, foreign investments in the sector, since Indian arms of foreign companies are entitled to bid for coal blocks and licences, as well as for commercial mining of coal.
