There's some talks of supplying Indian Maoist with the three holy grails of gorilla warfare:
Type 56 assault rifle (AK-47 clone)
Type 69 RPG (RPG-7 clone)
The downside to that idea is if Maoist actually took over India they might reform India into a credible threat.
India isn't that different from China in one way: the Chinese, after the fall of the Qing Empire, tried to hold on to all the possessions the Manchus controlled, keeping everything except perhaps Taiwan and certainly Outer Mongolia. India, likewise, tried to annex as much of British India as possible, with some cynical researchers suspecting what the Indians really can't forgive the Pakistanis for is splintering off highly Muslim areas of India instead of putting it into their control.
But India as a unitary state is in fact highly unnatural. The British colonialist achievement was to connect almost the entirety of the Indosphere under one government, even reaching out into boundary regions like Burma, which could be seen as the traditional Indo-Chinese cultural frontier. Before the British, however, no other Indian polity controlled the same extent of territory; Indian logistics made it so that it became extremely difficult to push through the jungle or the desert to an extent that a full empire could be ruled, even the Mauryas and Mughals never controlled the same extent as the British did.
And that, to an extent, is a huge disadvantage for India. India is partially unified by a shared cultural background (Hinduism and reactions to Hinduism), but regional diversity and rivalries make it difficult for India to be governed as a unified state, with major economic and social differences between the North and the South, the West and the East.
