WASHINGTON — US President Joe Biden on Monday sent President Katerina Sakellaropoulou a letter on occasion of Greece celebrating the bicentennial of the 1821 Greek Revolution.

In his letter, Biden underlined the fact that Greece is a key NATO ally and close friend of the United States, a country that provides stability and actively contributes to peace and prosperity in the Eastern Mediterranean, the Black Sea and the Western Balkans.

He also noted that during his political career he had the privilege of working closely with several Greek prime ministers and has also had long conversations with Ecumenical Patriarch Bartholomew.

Biden noted that he looks forward to continue the tradition of further strengthening cooperation between the two countries, and of reaffirming the joint commitment to the Transatlantic Alliance and to all the common values that unite Greece and the US.
