Well....
In international relations only nehruvian fools believe in things like brotherhood and mutual respect and cooperation...
The only thing that countries care about are their own interests..Now once China becomes India's largest trade partner and India does not happen to be China's largest trade partner...So even if you do not want to be the little brother..effectively you are what you are.....I would leave it to you to define your role...In the end it is about how much resources can the country generate and in what fashion....
Rather than getting into emotional rhetoric ... India would do better to exploit the situation any way she could...That is what every one else is doing.....
There is room for only one major power in Asia. India cannot become that power by being China's little brother. It can however achieve that status by being America's junior partner.
Its not always about trade. The US-China relationship should tell you a lot about that. You are an Indian advocating India becoming a Chicom-stooge? Get a grip. You sound like a CPI/CPM dumb-f***.
India will never get on the Security Council by being a Sino-Russian ally. It isn't in their "national interests" for that to happen. One doesn't have to be a Nehruvian idiot, one could just as well be a misinformed fool to advocate what you are saying.
