"Given this vital economic role, making the most of Asia's dynamism is of great interest to the entire world," Lagarde, on stage with Indian Prime Minister Narendra Modi, said.
"Increased interconnectedness means that Asia now affects the world more than ever before," she said. "By the same token, Asia is now more deeply affected by global economic developments than ever before -- and must respond to them."
With the global economy facing challenges, it is key that Asian countries carry out structural reforms to boost competitiveness and jobs and ensure growth in future, she said.
Lagarde cited examples including the need for China to rebalance its economy away from debt-led investment, the need for corporate governance reforms in Japan and for improvements in Indian infrastructure.
Strengthening the business environment and developing bond markets will be crucial across the region, she said.
Also speaking at the conference, Prime Minister Modi said that India has "dispelled the myth that democracy and rapid economic growth cannot go together".
India's government has projected economic growth of 7.6 percent for the financial year 2015-16, making it the world's fastest-growing major economy.
"My agenda of 'reform-to-transform' still needs to be finished," Modi said.
In January the IMF lowered its outlook for global economic growth this year, warning of substantial risks in major emerging market economies.
Slower Chinese growth, a stronger US dollar, collapsed oil prices and political turmoil could wreak further havoc in struggling economies like Russia and Brazil, putting the brakes on the global recovery, it said.
