Chinaís Premier Li Keqiang on Sunday began a three-day visit to India, his first foreign trip after assuming office in March. Bolstering Sino-Indian economic and trade relations, which saw below-potential expansion in the post-crisis years, is high on Liís agenda. In the few years prior to the onset of the global financial meltdown, India-China merchandise trade grew at a scorching pace, but the crisis indeed put the brakes on it, even as the potential of South-South trade all along needed no emphasis. FE sifts through the economic areas China and India would want to strengthen their engagement in a series starting today. For New Delhi, the widening of the trade deficit ($31 billion in April-December 2012-13) it runs with Beijing is a cause for concern, even as China looks to increase its market access and weighs investments needed to capture Indian market.
