Enemy of my enemy is my friend. And the Chinese were the one who made the mistake of making an enemy of the countries in the Pacific. You are just being repaid in your own currency.
And still most of your major investment capital comes from Japanese companies. Even after calling yourself the Dragon of the east and all you are still afraid of an Indo-Japanese deal in buying a few US-2i planes whose primary role is humanitarian? Did they ever teach you how to interpret things?
We have 1000s of Islands in the Indian ocean region and they are countries which might need our help in case of any natural disasters. Hell I think we need atleast 50 of these planes to have good connectivity to all those remote islands thus improving our capability to respond to any kind of natural and man made disasters in this region.
