An image of US President Joe Biden greeting Indian prime minister Narendra Modi has caught the fancy of social media users.

Biden appears to be giving a salute to Modi who is looking confident and relaxed in his response, seated with other world leaders in Bali

Indian right wing is in raptures, showcasing it as another sign of Modi's global standing.

Is Biden really saluting Modi? It is most likely a jocular gesture. But it does underline the good rapport between the two.

Will these friendly gestures translate to a warmer Indo-US relationship though? Only time will tell.
