Ukraine's President Volodymyr Zelenskiy said on Thursday he would be ready to jointly open an investigation into any possible Ukrainian interference in the 2016 USA presidential election and into Burisma gas company, which had a son of Vice President Joe Biden on its board.

Officials said that within hours of the 9 a.m. conversation, a rough transcript compiled by aides had been moved from a widely shared White House computer network to one normally reserved for highly classified intelligence operations.

Zelenskiy appears to be playing to both United States political camps to ensure Ukraine has continued support no matter who wins the presidential election next year.

The former US vice president has denied using his influence in 2016 to prevent Ukraine from investigating his son's involvement and has said he and his son have done nothing wrong.

Zelenskiy told reporters that Trump didn't blueprint to blackmail him all over a telephone name in July or a gathering in September.

Even before the call, security officials were concerned with the removal of the United States ambassador to Ukraine in May, efforts by Trump's personal lawyer Rudy Giuliani to spread conspiracies involving Ukraine and indications that Trump wanted Zelensky to offer up potentially damaging information about Biden, according to the newspaper. He said the Ukrainian stenogramme of the conversation matched the English one. He said he "didn't even check" whether the Ukrainian transcript is the same, but "I think they match". However, contrary to the accusations, a newly uncovered memo suggests no military aid was mentioned, ruling out quid pro quo allegations.

Zelenskiy said Ukraine would investigate because otherwise we "can't say yes or no" as to whether there was any such interference.

Zelenskiy added that the phone call "wasn't linked to weapons or the story with (Ukrainian gas company) Burisma", which is at the center of the controversy involving Biden.

"And we are in a position to examine interference within the (2016) election from the Ukrainian aspect, if it took notify".

"We are now looking again at all cases that were closed or broken up or were investigated earlier to make a decision to reconsider those instances where illegal procedural decisions were made", he said.

The Ukrainian reporters present were more focused on domestic issues, including Mr. Zelensky's ties to oligarch Ihor Kolomoisky, who owns the TV channel that helped propel Mr. Zelensky to countrywide fame ahead of his May election win with a show calledServant of the People, on which he played a fictional President of Ukraine.

Most of the questions at Thursday's unusual media event related to the Russian Federation conflict or Ukraine's economic troubles.

Zelenskiy met with journalists in groups of about 10 on the second floor of a hip food hall built in an old factory in Ukraine's capital.

Trump responded to Zelensky's comments as well, saying on Twitter that he had done "nothing wrong".
