Time to time /leftypol/'s lack of knowledge of South Asian politics with threads getting hijacked with members of diaspora is not a new phenomenon.
India, all the memes aside is still a potential threat militarily to China in the region. Recently India has acquired Rafale jets and is part of QUAD, an alliance that includes USA, Japan and Australia (https://en.wikipedia.org/wiki/Quadrilateral_Security_Dialogue
). India has active mountain corps as seen in recent border clashes with China and is improving infrastructure across the border areas by building roads, tunnels and bridges in Kashmir and North East. India in recent years has came militarily closer to USA with its annual 2+2 dialogs and Strategic partnership by signing treaty that allows exchange of crucial military information (https://indianexpress.com/article/explained/beca-india-us-trade-agreements-rajnath-singh-mike-pompeo-6906637/
). This is crucial because prior to this India had mostly stayed away from having explicit relationship with US.

Indian Ocean has a very strategic significance for Belt and Road Project. Which is why China is creating a "string of pearl" by building ports and entering in partnerships with Island nations there (Sri Lanka, Maldives) and Bangladesh and investing heavily in Gwadar port to have a strategic upperhand in case India easily chokes the route.https://www.indiatimes.com/news/india/here-is-all-you-should-know-about-string-of-pearls-china-s-policy-to-encircle-india-324315.html
It should be noted that due to fighting insurgency in Kashmir, India has managed to raise a corp of experienced troops who can fight in the mountainous terrain, which forms most of the theater with China. Recent clash has apparently surprised PLA regarding India Army's preparedness to tackle, as it managed to reach the Mansarovar Range in previous clash around Galwan Valley. Which is why China is focusing on building more air strips in Tibet, and making more settlements at bordering areas such as Dokhlam so it can overlook the sensitive Siliguri Corridor - a thin strip of land that connects rest of Indian Mainland with it's North Eastern Region.
I don't know how much role India is playing in political tussle in Nepal, but is not sitting idle for sure.
