"The kind of major structural and fundamental reforms undertaken in the country so far are truly global, they are really big," he said, adding that the Goods and Services Tax (GST) transformed the indirect taxation system in the country and the Insolvency and Bankruptcy Code is transforming the way the country resolves its non-performing assets.
Also, the RERA (Real Estate (Regulation and Development) Act) has transformed the realty sector. National biometric ID Aadhaar has institutionalised how to deal with people's identity. He also cited the recently promulgated legislation on dealing with economic offenders fleeing the country.

Fitch had on Friday retained India's sovereign rating at BBB-, the lowest investment grade, with a stable outlook, saying weak fiscal balances continue to constrain its ratings. It had cited government debt amounting to 69 per cent of GDP in 2017-18 to buttress its point.
The government had made a strong pitch with Fitch for an upgrade in ratings after rival Moody's Investors Service in November last year gave the country its first sovereign rating upgrade since 2004.
Fitch had last upgraded India's sovereign rating from BB+ to BBB- with a stable outlook on August 1, 2006.
Fitch had changed the outlook to negative in 2012 and then again to stable in the following year, though it kept the rating unchanged at the lowest investment grade.
While Moody's had in November 2017 raised India's sovereign rating from the lowest investment grade of 'Baa3' to 'Baa2' -- the first upgrade in almost 14 years -- and changed the outlook from stable to positive, S&P refrained from upgrading the rating from 'BBB-' citing high government debt and low income levels. S&P has maintained 'BBB-' rating on India since 2007.
