The United States supports creating two permanent United Nations Security Council seats for African states and one seat to be rotated among small island developing states, U.S. Ambassador to the U.N. Linda Thomas-Greenfield will announce on Thursday.

The move comes as the U.S. seeks to repair ties with Africa, where many are unhappy about Washington's support for Israel's war in Gaza, and deepen relations with Pacific Island nations important to countering China's influence in the region.

Thomas-Greenfield said she hopes the announcement will "move this agenda forward in a way that we can achieve Security Council reform at some point in the future," describing it as part of U.S. President Joe Biden's legacy.
