"We are not going to give up," Mittal said, expressing disappointment at the "progress made so far."

ArcelorMittal wants to cash in on the demand for steel in India but said it is constrained by the delays in getting mining and environmental clearances for the projects.

"We are losing the opportunity of participating in India's growth. We are committed to the country. We have been working on this project for several years. We have a team already in India which is all the time working on it," he said over phone.

Asked if the company is considering acquisitions, Mittal said, "takeover is not the idea for India."

The world's largest steel producer is working on modalities to set up two 12-million tonnes per annum steel mills, one each in Jharkhand and Orissa.
