President Joe Biden was received on Tuesday by King Philippe of Belgium at the Royal Palace in Brussels, where the monarch has his working office.
Both were accompanied by the Belgian Prime Minister, Alexander de Croo.
Biden arrived around 11:00 local time (13.00 GMT) at the palace and had a short chat with the monarch in front of journalists, before signing the guest book.
Afterwards, the U.S. president, the king and the prime minister retired for private talks.
Biden met with King Felipe as part of his first international trip to Europe since he arrived at the White House.
The tour began on the 9th in the United Kingdom, where the president had the opportunity to participate in the G7 summit in Cornwall and was received by Queen Elizabeth of England on Sunday at Windsor Castle.
