Despite recent jitters in emerging markets, the CEBR said China, India and Brazil would continue to catch up with the developed world. It described India's rise and young workforce as "unstoppable". The country is expected to overtake the UK in 2018, and Japan in 2025 to become the world's third largest economy. "The figures show the dramatic changes taking place in the world's economic geography," said Douglas McWilliams, chief executive of the CEBR.
