Tata Group Chairman Ratan Tata, Infosys Technologies CEO Nandan Nilekani, Wipro Chairman Azim Premji and Reliance Industries Chairman Mukesh Ambani are the four Indians in Asia's 25 most powerful business leaders list by the Fortune magazine.
Ratan Tata is ranked 12th most powerful Asian business leader, just ahead of Nandan Nilekani, who has been ranked 13th. Mukesh Ambani has been ranked 17th on the list by the magazine, followed by Azim Premji at 19th.
While Ratan Tata was not in the list in 2004, Nilekani has moved up to the 13th spot from 23rd. Mukesh Ambani has dropped to 17th from 13th, while Premji slipped from 10th to 19th spot.
Fortune said Ratan Tata, 67 'shows no signs of slowing down.' 'In the past year, he has been busy buying companies in Korea, Singapore, and Africa.'
The magazine described Nilekani as 'one of the architects of India's IT revolution' who earned himself a starring role this year in American journalist Thomas Friedman's best-selling book The World is Flat as the man who first suggested that the world is being flattened by new technologies.
Samsung Electronics CEO Jong-Yong Yun heads the list having been ranked Asia's most powerful business leader.
The list also includes Saudi Aramco boss Abdallah Jum'ah, LG Electronics CEO Kim Ssang Su, Sony CEO Howard Stringer and Toyota boss Katsuaki Watanabe.
