Whatever comments you have replied on, your ambitions have just been exposed.
Actions speak louder than words. China has had border disputes with all its neighbours which shows that it is interested in expansionism and imperialism, not India.
To this day, Chinese negotiators have refused to exchange boundary maps showing their perception of the border, while India has constantly tried to resolve the issue by telling China what their perception of the border is. Since you don't share your perception of the border, it becomes easy for you to make absurd territorial claims against India, and keep the conflict perpetually simmering. That is of course, in your best interests, since you don't want India to challenge your hegemony in Asia, but you'd have to be stupid to think that Indians don't understand the game that you're playing.
China has even gone back on agreements that stipulated any decision to delineate the border must not displace settled populations.
If there is tension today between India and China, it is entirely of China's making. Your totalitarian government has for decades believed its own propaganda that China is and should remain the supreme power in Asia and they have tried to do everything to make it so. The ambitions of China are no different than those of Imperial Japan in the early 20th century. The only difference is that China faces strong neighbours that cannot be defeated easily, and hence this game of cat and mouse that is being planned in the CCP headquarters.
After decades of insisting that Kashmir was an issue between India and Pakistan (even though Aksai Chin, which is part of Kashmir, has been occupied by China), China has started issuing separate visas to residents of Indian Kashmir than those granted to Indians from the rest of the country.
If India started issuing different visas to Tibetians and Uighurs than the ones given to other Chinese, your government would practically term it an act of aggression against China and threaten India with dire consequences as you often like to do. But to date, there has been no explanation of this new visa policy for Kashmiris.
All the above coupled with the blocking of the ADB loan, trying to scuttle India's admission to the NSG, arming Pakistan with nukes etc is enough evidence for even a blind man to see that China doesn't want peace with India.
So who has what ambitions is quite clear, and no amount of out-of-context accusations against anyone else will change that.
