Economic growth in emerging market economies slowed in the July-September quarter on poor performance by the manufacturing sector, but India expanded more than China, an HSBC survey said. The HSBC Emerging Markets Index (EMI) slipped to 52.1 in the third quarter this year, from 53.2 in the April-June period. A relatively better performance from the services sector was offset by the poor performance of the manufacturing sector, as global demand softened. However, among the big-four emerging markets, expansion in India and Russia were better than Brazil and China, HSBC said.
