President Katerina Sakellaropoulou also expressed her certainty that Greek-US relations will become even stronger during the tenure of US President Joe Biden, during her speech at a special event organized by the US Embassy, held in Athens on Wednesday.

The event has held in the context of the "Greece-US: Celebrating 200 Years of Friendship" campaign, and Sakellaropoulou was invited by US Ambassador to Greece Geoffrey Pyatt at the ancient Athenian Agora to mark the Wednesday inauguration ceremony of the Biden administration in Washington DC.

"Today is an important day, not just for the United States of America, but for the entire world. I am very glad that we are at the ancient market of Athens, the place with the highest symbolic value for democracy. I would like to extend my warmest congratulations to President Biden and Vice President Harris, and I am confident that the friendship and cooperation between the two countries will become even stronger," said Sakellaropoulou.

Ambassador Pyatt highlighted that "President-elect Biden is a friend of Greece who knows this country and its people well. The President-elect’s national security team has broad experience in this region and is deeply committed to our transatlantic relationship."

"With today’s historic inauguration and the peaceful transfer of power it entails, we turn a new page in the United States, and we look forward to Greece’s bicentennial and the upcoming year as an opportunity to reaffirm our shared democratic values and converging strategic interests," Pyatt concluded.

Foreign Minister Nikos Dendias in a post on Twitter on Thursday congratulated US President Joe Biden and Vice President Kamala Harris.

"Warm congratulations to new President Joe Biden and US Vice President Kamala Harris," Dendias said, posting a 2009 photo with then-US Vice President Joe Biden as he represented the government at the White House event for the celebration of the anniversary of 1821.

"Our relationship is at the highest point ever. Looking forward to a fruitful and productive relationship with President JoeBiden and Secretary of State nominee Antony Blinken. The US is a crucial partner of our country, with whom we share a common strategic vision," he added.

MeRA25 Secretary-General Yanis Varoufakis expressed his view that US President Joe Biden, who was inaugurated on Wednesday, is himself too part of the politics that gave rise to the Trump phenomenon, unless evidence to the contrary arrives soon, he said in a post on social media.

On Twitter, Varoufakis wrote in English: "Trump is out, thank goodness. Eagerly awaiting evidence that I am wrong to see Biden as the representative of a ruling class that fueled Trumpism – and is dead eager to continue to do so by doubling down on socialism for themselves and austerity for the rest."
