Prime Minister Manmohan Singh [ Images ] is expected to address leading business leaders from the US, EU, Middle-East, China and Pakistan at the 20th India [ Images ] Economic Summit starting from December 5.

The 3-day summit is also expected to see Finance Minister P Chidambaram [ Images ], Planning Commission Deputy Chairman Montek Singh Ahluwalia [ Images ], Commerce Minister Kamal Nath [ Images ], IT and Telecom Minister Dayanidhi Maran [ Images ] and Agriculture Minister Sharad Pawar [ Images ] putting up a concerted effort to woo global investors.

The World Economic Forum and Confederation of Indian Industry, the co-sponsors of the summit, have already sent invitations to the PM and other ministers, WEF director Colette Mathur said in New Delhi [ Images ] on Wednesday.

India Economic Summit is likely to be a gala event this year as many top businessmen of the world are looking towards India as a potential market for investment, she said.

"So far, CEOs of global conglomerates were eyeing China. This year, to my surprise, there is a big change and too many companies are willing to come to India," Mathur noted.

After 5-6 years, the summit is expected to see a team of Pakistani businessmen headed by its commerce minister, she said.

"It will be for the first time the summit will devote a significant time specifically for South Asian nations -- India, Pakistan, Bangladesh and Sri Lanka [ Images ]," Mathur said, adding they will discuss how to make this region a dynamic economic hub by 2020.

"If they cooperate among themselves, their performance will be better," she added.
