Union Finance Minister Arun Jaitley has said that India's 7.5 per cent economic growth rate is not its best potential growth rate and there is restlessness in the Narendra Modi-led government to boost economic growth. Talking to CNBC News Channel in New York, Mr. Jaitley stressed that a series of reforms aided by a lot of investment particularly in infrastructure, improvement in manufacturing, agriculture will help push up India's economic growth. Predicting an 8 per cent growth this year, he said the government will set higher GDP growth targets in the future. When asked about the concerns over what is termed as "renewed tax terrorism" in India, Jaitley said this is a term coined by him and it is his responsibility to make sure that it does not happen in India again.
