U.S.-Russia talks have expanded to a proposed multibillion-dollar Lukoil asset deal, NYT reports.

Reuters, citing the New York Times, reported that discussions between the Trump administration and Russia now include a potential deal for a portfolio of Lukoil assets. The group pursuing it reportedly includes U.S. investor Todd Boehly, two Middle Eastern groups and an arm of the U.S. government.

The White House, U.S. Treasury and Lukoil did not respond to Reuters requests for comment outside regular business hours. The proposal remains contingent on U.S. and Kremlin approval and has not been announced as a completed transaction.
