Frankly, I wouldn't mind increasing trade with bharat. Trade after all is a win win situation for every one involve. You buy something you need. But yeah, I'm not sure there is much to buy from India. India is famous for exporting generic drugs, something that China certainly need. But Indian cough medicine scandal is certainly a good lesson of not trusting Indian drugs. Not to mention I also think China should pursue this generic medicine businesses itself, especially since India rely on China for generic drug raw material.
The way India treat Chinese investment in India also make me thing that Chinese companies should just reduce or even avoid India altogether. It is better for China to invest in Bangladesh or Pakistan. China can use Bangladesh as export base to Indian market.
