Joe Biden, in his last major speech as U.S. vice president , called Russia the largest threat to the international order Wednesday, predicting that Moscow will attempt to interfere in elections held in Europe in 2017.

"Under President [Vladimir] Putin, Russia is working with every tool available to them to whittle away at the edges of the European project, test the fault lines of western nations and return to a politics defined by spheres of influence," Biden said, speaking in Davos, Switzerland at the World Economic Forum.

Biden argued that "it's not just the United States that has been targeted" by Russia.

"With many countries in Europe slated to hold elections this year, we should expect further attempts by Russia to meddle in the democratic process. It will occur again, I promise you. And again the purpose is clear: to collapse the liberal international order."

Russia denies the allegations that it interfered in the U.S. election and WikiLeaks founder Julian Assange denies Moscow is his source. Russian Foreign Minister Sergei Lavrov turned the allegations on their head, arguing the European Union was more responsible, not the Kremlin.

"It is not Russia but the European Union that has interfered in the U.S. election. The leaders of EU states have made it clear they supported Hillary Clinton and demonized Donald Trump," Lavrov said Wednesday.

Slated to be inaugurated on Friday, U.S. President-elect Donald J. Trump is not at the Davos conference, widely seen as a confab of the global elite . Trump sent incoming White House advisor Anthony Scaramucci, a Wall Street veteran, in his place.

The Hill newspaper noted Scaramucci gave an interview to Russian state news Wednesday. The interview comes at a time of continued suspicion regarding Trump's ties to Moscow; Putin said Tuesday he had never met Trump personally.

"What the new American president is saying is that he has an enormous respect for the Russian people and the legacy of the relationship that the U.S. has with Russia, which dates back to the Second World War," Scaramucci told TASS news agency. "He has enormous respect for the Russian people and Russian culture and so he is signaling that, hopefully, whatever the hostilities may be, perhaps we can improve them over the coming years."

Scaramucci defended the president-elect's continued practice of matter-of-factly tweeting his thoughts.
