New Delhi, June 24 (ANI): Finance Secretary, Arvind Mayaram, on Tuesday laid emphasis on the need to boost investors' confidence to bring the country back on the path of growth and to spur economic expansion to its potential level. India will likely raise the foreign investment limit in government debt soon, as almost all the allocation has already been taken up as overseas buyers pile into the country's financial markets. The finance ministry will decide on the matter after consultations with the Reserve Bank of India and capital markets regulator Securities and Exchange Board of India. Mayaram said he is hopeful that the government would take adequate steps to boost overall growth rate.
