The US State Department said in a statement that Pompeo's visit to Greece is part of a European tour that he will undertake between September 27 and October 2, and will also include all of Italy, where he will also have a station in the Vatican during which he will discuss the file of religious freedoms, and Croatia.
On his second visit in less than a year to Greece, the US Secretary will travel to Thessaloniki (in the north) and Crete, where he will meet with the Greek Prime Minister, Kyriakos Mitsotakis.
The US State Department stated that while in Greece, Pompeo would stress Washington and Athens' commitment to "promoting security, peace and prosperity in the eastern Mediterranean," and "will celebrate the strongest Greek-American relations in decades."
While in Crete, the US secretary will visit the NATO naval base in Souda Bay.
Pompeo visited Cyprus two weeks ago, where he urged Turkey to stop activities that cause tension in the eastern Mediterranean, calling on all parties to pursue diplomatic means.
There is a dispute between Turkey on the one hand and Greece and Cyprus on the other hand over oil and gas resources in the eastern Mediterranean, which raises fears of a more intense conflict.
The dispute escalated on August 10, when Turkey sent a ship to explore natural gas and warships to waters contested by Greece, and the tension culminated in late August, when the two countries held parallel military exercises.
However, the level of tension between Greece and Turkey decreased, on Tuesday, as the two countries announced their intention to resume bilateral negotiations soon.
