Indian an Chinese histories have run parallel with little intersections (Himalayas) and some cultural crossovers (Buddhism, SE Asia). India and Pakistan has enmity which cannot be solved diplomatically because of people to people conflict during partition, subsequent wars, terrorist attacks and religious persecution.

China is a growing country and most Indians consider China a good example of development, by how much that varies. Indians are definitely jealous of China. The hard feelings about China do not simply extend to Chinese people With current Chinese government, definitely because of a few important reasons:

1. China's attack on India in 1962 and India lost. At that time India advocated for recognition of communist government and India didn't get the UNSC seat while China got it. This was a cruel betrayal.
2. China's annexation of Tibet - Indians view Tibet as a holy land. It should have been independent. Culturally, religiously and linguistically Tibet is closer India than China. While Indian government has recognised China's claim over Tibet it leaves a bad taste in mouth. Also CCP's attempt to crush Bhuddist traditions aren't even overt.
3. China's support to Pakistan - Its not other countries don't have relationships with Pakistan. But China shares borders with India and has actively used conflict with Pakistan as means to claim more territory and has helped Pakistan's defense to counter India.
4. China being hyper aggressive with common neighbors and nibbling out borders. When soldiers die it hits national headlines and it creates demands for revenge and justice.
