The President of the United States, Donald Trump, threatened Russia with secondary trade tariffs if the Kremlin does not agree to end the war. RBC-Ukraine analyzes under what conditions this pressure tool could be effective and what the chances are that it will influence Russia’s position.

Trump said the United States would put secondary tariffs on countries that do business with Russia if a peace deal is not reached in 50 days.

The change in Trump’s approach may also mean that the $US8 billion (£6 billion) of frozen Russian assets in the US (and US$223 billion in Europe) could be released to aid Ukraine, which would provide a ready means to pay for the US arms transfers.
