The Third Railway Survey and Design Institute Group Corporation, a subsidiary of the China Railway Corporation (CRC), will work with Indian firms, dispatching rail experts to initiate the study for the route.
India has invited global tenders for three high-speed rails, including the New Delhi-Mumbai railway, in December and attracted 12 consortiums from seven countries bidding for the contracts.
China is already conducting feasibility study of the New Delhi-Chennai corridor.
CRC said China's railway technology is reliable and adaptive and has lower price/performance ratio, state-run Xinhua news agency reported.
