Well the US is a maritime strategic competitor (or adversary) that China would have to live (and pretty much deal with for all matters) with for decades to come. The US-China Relations will likely swing back and forth between limited armed conflict (Taiwan or Diaoyu/Senkaku) and strategic stability (healthy competition, if you want to put it nicely), but neither side would try to destroy one another as long as both have credible nuclear deterrence. However, Taiwan is an issue that matters directly to the CCP's legitimacy and maritime security, so it would have to be dealt with eventually. India is a latent power and rising quickly had it not been the virus. Yet, it will another two decades before India could match China, so it is better to strangle it before it becomes too powerful. Also, India's nuclear deterrence remains limited, it is worth to the risk to snatch Arunachal Pradesh, Kashmir (and give to Pakistan afterward), and carpet bomb Dharamshala with thermobaric ordinance (put an end to the Tibet issue once for all, as well as uprooting the grave of Lord Elgin, the man who burnt the Summer Palace in 1860). In other word, the next five year would be the ideal time to knock India down and delay its rise. Beijing could also airdrop weapons and fuel to the Naxalites, and strategically promote Cultural-Revolution like Maoist radical campaign for the Naxal supporters, such as encouraging land reforms through killing landlords and Brahmin Priests. In other words, underline India similar to how the US tried to undermine China and USSR during the Cold War. Use a combination of "peaceful evolution," limited military campaigns, influence operations, and various sabotages.
