i dont think you can make such a comparison among countries that have nukes..
Also India has a much bigger and imminent border dispute with Pakistan than China..
the only threat from China for India is economical and ideological (red corridor of india)
No...I do not agree with your assumption...I am very much sure, with economic prosperity as the primary driver, India and Pakistan may try to fool their people in creating an atmosphere of war, but in reality, no country every venture out to change physical boundary that exists today. The classic example was last year when so many incident has happened that could have triggered an all-out war between both of us...But it eventually did not happen...Even if any war would happen, India at this point of time, is not much worried about it as there are multiple factor that will influence India and Pakistan to maintain the status quo...But for China, it is a separate case altogether...China is a global power that can not be influenced by anyone as India/Pakistan which will be influenced by Arabs/West and China to avoid any kind of war in the future...
