If Chinese share goes down from 20% to 19% then Indian output should be 2% of world trade which may go upto 3 % giving 50% boost. This 10 times ratio is quite shameful and clearly tells that China was given more business for some very good reason.
On the other hand why is the trader interested if India cannot handle the extra business. He should be more careful in analysing if his business can take more orders and not worry too much about others. Also he needs to be more careful that his products don't get rejected!
