Andhra Pradesh is set to house India's first national investment and manufacturing zone after the state assured the Centre of the availability of 2500 acres (10 sq km) of land in one place in Prakasam district. The imminent final approval for the NIMZ, which is expected to give a fillip to the Prime Ministers Make in India campaign, comes four years after the concept was mooted to boost manufacturing in the country and two years after the Department of Industrial Policy and Promotion gave an in-principle nod to Andhra Pradesh in this regard.
