The meeting comes as the US president looks to solidify his diplomatic legacy before the end of his term in early 2025.

Leaders of Australia, India, Japan and the United States will announce plans for new security initiatives in the Indian Ocean on Saturday, when outgoing U.S. President Joe Biden hosts counterparts from the Quad grouping established due to shared concerns about China.

Senior Biden administration officials told reporters ahead of the meeting that the leaders would announce plans to expand an Indo-Pacific Partnership for Maritime Domain Awareness, launched two years ago to include the Indian Ocean region.
