first of all
while ukraine might still be a russian client were it not for outside interference,
but pakistan needs zero outside input to be a rival to india, china did not turn pakistan into an anti-indian state, it was that from the beginning
in addition, china is a far more useful ally to russia than india anyday of the week, there are no border disputes, and china is far more powerful across all spectrums than india, and both share the goal of balancing against america, the economies are very complementary, the situation may change in the far future where china becomes as dominant as america is today, but that's far off at best, and may never happen.
in fact india has no real reason to be rival to china either, were it not for the bad blood sown by nehru, if he had bother to negotiate the border issue would have been solved decades ago (zhou enlai hinted that the line of control then would have been acceptable to china).
on the p5 issue, not happening so long as india has thrown its lot in with japan.
