World Athletics President Sebastian Coe said he was delighted with India's interest in hosting the 2036 summer Games but cautioned the South Asian nation that organizing an Olympics was one of the world's most complex projects.

Coe, 68, a two-time Olympic champion in the 1,500 meters, is one of seven people bidding to replace Thomas Bach as the next president of the International Olympic Committee.

India is a growing sports power but has never hosted the Olympics. Its capital, New Delhi, hosted the Commonwealth Games in 2010, a $6 billion event billed as Delhi's answer to the Beijing Olympics.
