U.S. President Joe Biden will host the leaders of Japan, Australia and India in Washington next week for the “Quad” grouping’s first in-person summit, the White House has announced, with China’s growing assertiveness expected to be high on the agenda.

The meeting, the first since online talks between the four countries’ leaders in March, will also be a chance for outgoing Prime Minister Yoshihide Suga to assuage any continuity concerns among the grouping as he prepares to step down from his post just days after the summit.

Biden will hold talks with Suga, Australian Prime Minister Scott Morrison and Indian leader Narendra Modi on Sept. 24 at the White House, spokeswoman Jen Psaki said in a statement Wednesday.
