I never told that Chinese hate Pakistani's, They are indifferent! Pakistan is the last thing they think! They envy the Americans and want their place! They love Bill Gates and Steve Jobs kind!
All China has with Pakistan is to keep a check on India! The day when Pakistan becomes useless in countering India or when there is a rise in terrorism emanating from Pakistan affects China! Then you will know the true picture!
Also it does not mean that China will come to Pakistan's aid in its war with India! They will not risk eat up nukes for Pakistan's benefit! Not happened in the past, Not going to happen in future!
