U.S. Secretary of State Marco Rubio will begin a diplomatic tour this Monday visiting Iceland, Greece, and Portugal, featuring an agenda focused on security and economic cooperation.

Rubio will start his trip in Iceland, a strategic North Atlantic nation, where he will meet in its capital, Reykjavik, with "officials to address collaboration on economic and security matters," according to an official statement.

Subsequently, the chief of U.S. diplomacy will travel to Greece leading an American delegation to participate in the sixth Strategic Dialogue between the two countries, the primary bilateral political coordination mechanism established in 2018.

The meeting will seek to "deepen" cooperation in defense, regional security, and energy, the statement added.

Rubio will conclude his tour, which will extend through Thursday, October 8, in Portugal, where he is scheduled to advance a cooperation agenda spanning defense, economics, and technology, the State Department noted in the release.

The trip takes place within the framework of Washington's coordination with European NATO allies, with whom Rubio will discuss regional and energy security as well as military cooperation.
