Facebook chief executive Mark Zuckerberg has been known to hold town hall-style Q&As, but later this month, he will hold one with a special guest: India’s Prime Minister Narendra Modi, VentureBeat reports.

The country’s 15th prime minster and the leader of the world’s third largest economy will chat with Zuckerberg about social and economic challenges on September 27 and Zuckerberg is encouraging users to submit questions.

Answering questions from the social network’s 1.49 billion monthly active users isn’t new for Zuckerberg. It will be the second town hall event that he’ll be doing this month — this Tuesday, September 15, he is hosting one where the questions will be entirely about Facebook. The second one with Modi will be just another Q&A event with a world leader — and Zuckerberg has done a few with some powerful people.

With the Modi town hall, the focus will be about challenges faced by India and likely how the world can collaborate to face them together. Appealing to one of the most populated countries might also be a motive for Zuckerberg, especially as Facebook keeps pushing its Internet.org initiative.
