Finance Minister Arun Jaitley has said, remonetisation, following the world's largest note ban, has been substantially completed and the move will result in expansion of the tax base in the country. Speaking at an Interactive Session on Indian business environment in Tokyo, Mr. Jaitley said, 86 percent of India's currency was replaced within a matter of few months and the move brought about a far greater movement towards digitisation. The finance minister also said that India clocked between 7 and 7.5 per cent economic growth rate even in an adverse global environment. He said over the next decade or two, the avenues for investment in India for long-term safe investments are going to be plentiful. Mr. Jaitley said the government has systematically addressed the challenges facing ease of doing business in the country including getting environmental clearances.
