India is a part of 10 Asian economies which will move past the US in GDP terms by 2030. The group may grow such robustly, on aggregate, and amount to more than $28.35 trillion in real GDP (2010 constant dollars) terms, while for the United States will amount to $22.33 trillion, but a few concerns remain. \u201cWe expect Asia-10 to pull ahead of the US by 2030,\u201d DBS report said, but added that this neither is a sufficient nor a necessary condition to invest in Asia, as investing cannot be based on a single indicator, especially when it comes to a long-term horizon. The countries are: China, Hong Kong, India, Indonesia, Malaysia, the Philippines, Singapore, South korea, Taiwan and Thailand. Here are three major concerns: Trade war: The rise of protectionism may reduce investment flow in the region as Asia is one off the most externally exposed regions. The trade conflict may have a substantial impact on the outlook of the Asian economy, DBS said. Demographic dividend: DBS report also said that the Asian countries may have benefited in the past from the demographic dividend, but it\u2019s not such valuable now. Employment A young population creates a \u201cchallenge\u201d in terms of generating jobs, in absence of which there will be high levels of unemployment, creating both an economic and social\/political challenge, the report noted. \u201cCountries like India and the Philippines will need to work hard to create employment for its young population; while aging countries like Singapore, Japan and China may be able to offset the demographic drag through the active use of new technology,\u201d the report said.
