My assumption: last remaining Sentinelese flee to Thailand. Sentinel island is close to India and Thailand.
Not sure. The Sentinelese are very territorial and prefer to stay away from the rest of the world. This group, I can see some Asian features. But interesting my first time seeing them in Thailand.
I can imagine the conversation going something like this: "how's the living condition among the people? What are some challenges your community have and needs?

"
Too bad I don't speak Thai.
