You have to realise why Indians do not like the Chinese in fact many people from world dont like them too.
And when we say Chinese its not the common Chinese person but their power hungry , crazy rulers who think they want to rule the entire world.
If someone calls you brother and attacks you then there certainly is not going to be any love between the two.
We have had very bad experience with Chinese govt. till date, they behave rudely with us, back stabbed us, constantly helped Pakistan against us, grabbed our land and claim a huge piece of our current land.
And they forcefully took Tibet too, who cares what the Chinese think we think they are power and land hungry despots.
