The Quad Leaders' Summit this year was earlier supposed to be held in India, but US President Joe Biden was keen to hold the event in his hometown.

This will be a farewell summit for both Biden and Japanese Prime Minister Fumio Kishida as they near the end of their terms in office -- January 20, 2025 for the US president and Oct 1 for Japanese prime minister.

The fourth leader attending the meeting is Australian Prime Minister Anthony Albanese.
