Government is looking to tap funds from the UK, Saudi Arabia and Japan to finance the mega infrastructure ambition, with new structures to route the funds being discussed. Unlike the past when only broad commitments were taken, this time, the finance ministry and Niti Aayog are offering a list of projects, such as a ring road around a tier II city or a large highway, to investors from other countries. Besides, the projects are sought to be designed in a way that the concerns of the investors are addressed, and they are also being offered equity in some of the special purpose vehicles to execute the projects, sources told TOI.
