Speaking at a meeting of the OECD Ministerial Council in Paris, Szijjártó called OTP's inclusion "absolutely unfair" and said the bank had "not violated any Ukrainian or international rules."

He added that keeping OTP on the list would pose "obstacles and challenges in terms of cooperation with Ukraine." The NACP included OTP on the list in May, citing the lender's exposure in Russia.

OTP said the measure was "completely undeserved" and rejected the agency's reasoning.

"OTP Bank condemns all aggression against sovereign states, including that against Ukraine, and is committed to supporting Ukrainian citizens and the country's economy," the lender said.
