Biden was declared president-elect two weeks ago in the election against Trump, who has insisted he didn't lose the elections. The president has claimed voter fraud and has directed his team to contest the votes in key states that cost him reelection.
Putin, who still hasn't congratulated Biden on his victory, said Sunday on Russian state TV: 'We will work with anyone who has the confidence of the American people.'

'But that confidence can only be given to a candidate whose victory has been recognized by the opposing party, or after the results are confirmed in a legitimate, legal way,' Putin stated.
Putin added that the choice to not congratulate Biden is 'a formality' with no further motives.

He also said that he thinks relations between the US and Russia have been 'ruined'.
When Trump won in 2016, Putin was quick to congratulate — though Trump's challenger in that election, Hillary Clinton, conceded the day after the vote, not like Trump himself.

Just days after the election was called in Biden's favor, Putin's spokesman Dmitry Peskov told journalists that this election is unusual.
'Obviously, you can see that certain legal procedures are coming there, which were announced by the incumbent president — therefore this situation is different, so we consider it correct to wait for the official announcement,' he said.

Peskov suggested that when the time comes, a congratulatory note from Putin would appear with all the expected protocol.
'I remind you that Vladimir Putin said more than once that he will respect any choice of American people, and will be ready to work with any chosen president of the United States,' he said.

For now, Putin's holding back provides a delay in addressing that fraught question of how to better relations.
Although Russian politicians generally praised Trump's election in 2016, expecting him to make good on his words of developing ties, his administration failed Moscow by enacting sanctions, expelling scores of Russian diplomats in the wake of the poisoning of double agent Sergei Skripal in the UK, and allowing lethal weapons sales to Ukraine.

Although Russia is characteristically suspicious of Democratic US administrations because they tend to be more forward about criticizing Russia on human rights and democracy matters.
'With the victory of a Democrat, one can expect revenge from all nonconservative forces around the world. This means more Russophobia in Europe, more deaths in (eastern Ukraine) and in many other hot spots of the world, as well as more politically motivated sanctions, if we talk about the direct and simplest consequences,' said Konstantin Kosachev, chairman of the foreign affairs committee in the upper house of parliament, whose opinions generally match the Kremlin's.
