"The mood around the world to invest in India is very positive. This will go up significantly," Jaitley said.
Defending the government's move to take the ordinance route for certain issues, he said that the government could not have sat back and waited for the Rajya Sabha to pass bills.
He said that the much-awaited Goods and Services Tax (GST) would be implemented next year.
The Modi government has, in recent months, allowed enhanced foreign direct investment (FDI) in the insurance and defence sectors, besides allowing 100 percent FDI in railways.
Jaitley said that the government will pursue its policy on disinvestment in public sector units (PSUs) in coming months.
