Khaled Elgindy, the director of the Middle East Institute’s program on Palestine and Israeli-Palestinian affairs, said that the decision to restore funding to the agency was “a very positive development” and would set an example for other countries as they decide whether to commit funds to it.

Despite that, Mr. Elgindy said that the move focused on reversing a Trump policy in the region — but did not yet appear to be part of a larger effort to advance the most difficult issues, such as discussions about a two-state solution.

“Their goal is to undo as much of the Trump legacy as possible,” he said, “and hope that that’s enough to sort of allow the issue to stabilize and not deteriorate.”
