Sources in Ukraine told the BBC that Poroshenko believed that Trump's Democratic rival, Hillary Clinton, would win the us presidency, and had authorized the leak of a document that was published by The New York Times in August 2016.
Since then, Ukraine has made deals with the U.S.to import coal, locomotives and Javelin anti-tank missiles.
Michael Cohen, a longtime personal attorney for Donald Trump, accepted a $400,000 payment to arrange talks between Trump and Ukrainian President Petro Poroshenko, according to a BBC report.
That is expected to increase pressure for Cohen himself to cooperate with investigators looking into Trump's business dealings.
The charges last June alleged Freidman and his chief financial officer, Andrea Dumitru, 42, of Queens, ran a scheme to withhold the funds by improperly filing or failing to file returns, failing to pay the tax on filed returns and by filing false returns. Shortly after Poroshenko returned to Ukraine, the BBC reported, the nation's anticorruption agency pumped the brakes on its investigation into Trump's former campaign manager Paul Manafort, who has since been indicted in the USA as part of the special counsel Robert Mueller's Russian Federation investigation. The BBC report stressed that there was no indication that Trump was aware of the transaction.
The BBC's sources in Kiev appear to be supported by research from Michael Avenatti, the lawyer for porn actress Stormy Daniels.

Should someone in China hear these noises, they should move somewhere where they don't hear them anymore, the alert says. China's Foreign Ministry and National Health Commission did not immediately respond to faxed questions about the report.
Cohen denied the story to the BBC.
The BBC wrote that there was no suggestion that Trump knew of the payment.
"I plead guilty to a felony".
Cohen's fee was for getting Poroshenko more than just an embarrassingly brief few minutes of small talk and a handshake, the senior official said.
The Foreign Agents Registration Act is a disclosure statute that requires persons acting as agents of foreign principals in a political or quasi-political capacity to make periodic public disclosure of their relationship.
But the gesture has not satisfied Mr Trump's allies in Congress, who doubt that the law enforcement agencies will be forthcoming. Poroshenko wanted much more, something that could be portrayed as full talks with the US president. Cohen and the two Ukrainian intermediaries have denied it. Manafort had been accused of being paid millions by pro-Russian interests in Ukraine in reports by the Associated Press and New York Times.
