World Bank modeling suggests that together China and India will serve as nearly twice the engine for growth as of the United States and the euro zone combined by 2025, the report said.
India, however, faces many of the same problems and traps accompanying rapid growth as China: large inequities between rural and urban sectors and within society, increasing constraints on resources such as food and water, and a need for greater investment in science and technology in order to continue to move its economy up a notch, the report said.
