The Maldonians, Atlantis, The 3 pirate lords we have a good relationship with(Nemo, Sinbad, Davy Jones), Moriarty in France, and we could even use this as the reasoning to finally approach China to warn them not to add to their mess.
I don't think we know enough about India to include anyone on that side of things though. The biggest politiee there we could ally with is a bunch of monkeys, Mowgli and friends, and a village under siege that Selous helped on his way to us iirc.
There is the option of telling the EITC, but we kinda hate them so probably not.
