India is poised to surpass the position of the world's third-largest economy by 2030, with its gross domestic product (GDP) expected to expand to $6.5-9 trillion, said Arvind Panagariya, the chairman of the 16th Finance Commission of India, on Thursday. "The fundamentals of the economy are absolutely solid. So, I expect us to return to at least about 7% economic growth," he added.
