Chinese delusions against India is not from today, its actually nearly 1400 years old.
According to Han fantasy, a Chinese diplomat named Wang Xuance conquered whole of India in 643 AD after Harshavardana's death. Then took the successor king Arunasva as a hostage and sent him back to Tang China as a gift to the Hanese emperor.
If indeed Hans ruled us Indians, there would signs in terms of inscriptions, changes to subcontinent language, cuisine, culture and architecture, language or script but no such evidence exist
Only Indian sources mention of King Arunasva repulsing an Arab invasion. No records exist of him fighting some wangu xuanxu
Parallelly, during this time Tibetan conqueror Songtsen Gampo was slaughtering Chinese and making inroads into Tang dynasty's lands

So, Chinese engaging in military action in India is impossible
This shameless lie was even gloated over by Mao in speeches to his gullible masses
Funny thing is, nearly a century later, Han's get squashed by Arabs and permanently lose Chinese influence in central Asia and Xinjiang for nearly 1400 years.
