What Happened: U.S. President Donald Trump will meet Swiss President Ueli Maurer to discuss a number of issues, including "Switzerland's role in facilitating diplomatic relations," according to a May 15 announcement by the White House.
Why It Matters: Switzerland serves as a formal diplomatic channel between the United States and Iran, and both sides will likely discuss ongoing tensions between Washington and Tehran during their meeting. Although Switzerland can play a prominent role in facilitating communication between the United States and Iran, it does not generally participate in negotiations like Oman or other European nations.
Background: Maurer recently visited China to convey his position on tariffs, trade and finance. Both leaders will likely also discuss the situation in Venezuela after the United States and Switzerland signed a protecting power agreement in April in which Bern will represent U.S. interests in Venezuela.
