AMMAN, Jordan — Vice President Joseph R. Biden Jr. held talks in Jordan on Wednesday with King Abdullah II on a variety of regional topics, including the fight against the Islamic State.

Jordan was the last stop on the vice president’s Middle East tour, which also included visits to the United Arab Emirates, Israel and the Palestinian territories.

Mr. Biden and King Abdullah also discussed “efforts to achieve peace between Palestinians and Israelis based on the two-state solution,” according to a news release issued by the royal court.

Jordan is an important ally for the United States in the region, and since the 1950s, the United States has provided it with more than $15 billion in economic and military aid. Last year, the Obama administration and Jordan’s government signed a three-year agreement in which the United States pledged to provide Jordan with $1 billion annually in total foreign assistance, subject to the approval of Congress, according to a report published by the Congressional Research Service.
