Russian company Uralkali has demanded a full reimbursement from Haas after being dropped as the team's title sponsor ahead of the coming Formula One season.
Haas cut ties with Dmitry Mazepin's company Uralkali and dropped his son, Nikita, as driver following Russia's military invasion of Ukraine.
Uralkali signed a deal with Haas at the start of 2021, a deal which included Mazepin's race seat.
Dmitry Mazepin is a close ally of Russian President Vladimir Putin and was one of the business leaders who met him at the Kremlin shortly after the invasion started.
Motor racing's governing body, the FIA, has not banned Russian drivers from competing, but last Saturday, Haas confirmed it had cut ties with Mazepin and Uralkali.
On Wednesday, shortly before Mazepin spoke to the media for the first time since that decision, Uralkali released a statement saying it wants its money back.
The statement said: "The Company views the Team's decision as unreasonable and believes that sports should always be free of politics and pressure from external factors."
In his media session, Nikita Mazepin said he is launching a new foundation -- named We Compete As One -- to support athletes who are blocked from competing for "political reasons."
He wants to support athletes who have "been collectively punished just for the passports they hold."
Uralkali wants to use the reimbursed money from Haas to set up that initiative.
Uralkali's statement added: "As most of the sponsorship funding for the 2022 season has already been transferred to Haas and given that the Team terminated the sponsorship agreement before the first race of the 2022 season, Haas has thus failed to perform its obligations to Uralkali for this year's season. Uralkali shall request the immediate reimbursement of the amounts received by Haas.
"The refund from Haas and the remaining part of Uralkali's sponsor financing for 2022 will be used to establish the We Compete As One athlete support foundation."
Haas declined to comment on the statement when asked by ESPN.
On Wednesday evening, Mazepin and his father were named in a list of European Union (EU) sanctions against Russia, meaning he would have struggled to compete at a large number of F1 events this year.
Mazepin said he learned of his "sacking," as he put it, from the news release Haas put out on Saturday.
Denmark's Kevin Magnussen has been confirmed as Mazepin's replacement.
