You mean Chinese has more naval presence in Arabian sea than India?
Sir Ji, you are seriously over-estimating Chinese.
Again, it all comes down to logistics, in Indian Ocean, Indian logistics challenge would be much simpler than the logistic challenges Chinese would face.
Sorry but I don't see Chinese helping you with boots on ground, Diplomatic and material support - definitely. but boots on ground, forget it. Not that it's not intriguing but Chinese are at best a bunch of cowards, have not seen a skirmish in decades.
More over their leadership knows any minor loss in war would mean the end of CCP as we know it.
