In a way Chinese leader visiting India is insinuating that India should not follow other countries who are objecting an encroachment of China in the South China Sea.  Also, he is hinting that if India does not follow what China is insinuating, there could be business repercussions.  I think India ought not to listen to China on this issue at all.  China never helped India on any international issue.  Why should India come to support China on this illegal occupation of international waters.  China should abide by the United Nations Tribunal judgment. India should not support China on any issue unless China first vacate Indian territory occupied by them in the Ladakh area, shun all claims on Arunachal Prades and start stamping Indian Passports for the people of Kashmir visiting China along with supporting India for the entry in the NSG.  As far as business tariff situation is concerned, it should always be reciprocal failing which there should not be any business agreement.  Choice should be of China what they want to do.  Do they want an acrimonious relationship with India or live in a friendly environment in that region?
