Andrew Adams, the prosecutor who heads the “KleptoCapture” task force, informed Reuters of the findings in an interview on Friday.

“There are efforts afoot—some of them publicly reported—to move, for example, moveable property in the forms of yachts, airplanes…into jurisdictions where, I think, people have the perception that it would be more difficult to investigate and more difficult to freeze,” Adams said.

The U.S. and Europe moved quickly to impose unprecedented sanctions against Russia after it invaded Ukraine in late February. The creation of the KleptoCapture task force came soon after the announcement of the earlier sets of sanctions to help ensure that the targeted entities and individuals truly felt their impacts.

Adams told Reuters that in addition to seeing evidence of efforts to evade existing sanctions, the task force has also seen evidence of efforts to move assets in anticipation of potential sanctions. He said that the “shared sense of purpose” between countries involved in probes against the oligarchs is at an “all-time high” as the world continues to respond to the Russia-Ukraine war.

Adams did not tell Reuters specifically what individuals were behind the alleged efforts to avert the sanctions or pre-emptively move assets. He also did not specify which jurisdictions had supplied information to the task force.

The Justice Department announced the creation of the task force on March 2, less than a week after Russia invaded Ukraine. Attorney General Merrick Garland said in a statement that the Justice Department “will use all of its authorities to seize the assets of individuals and entities” who violate the sanctions.

“We will leave no stone unturned in our efforts to investigate, arrest, and prosecute those whose criminal acts enable the Russian government to continue this unjust war,” he added.

Still, there have already been indications that wealthy Russians are attempting or successfully seeking economic refuge in other countries. Some, for example, have been funneling their funds into Middle Eastern real estate, with companies selling several properties in countries like Turkey and the United Arab Emirates every day.

Newsweek reached out to the Justice Department for additional comment but did not hear back in time for publication.
