The U.S. said on Monday it introduced new Iran-related sanctions ​on Russia's VTB Bank Public Joint Stock Company, accusing ⁠it of involvement ⁠in Iranian sanctions evasion, according to the Treasury Department, as Washington seeks ​to further step up ​economic pressure ⁠on Tehran.

The action builds on sanctions imposed against VTB, Russia's second-largest lender, in 2022, when the bank was targeted following Moscow's full-scale invasion of Ukraine.

"Under Operation Economic Outcast, Treasury will continue to target and disrupt those who provide material, technological, or financial ⁠support ⁠that allows the Iranian regime to sustain its terrorist enterprise," U.S. Treasury Secretary Scott Bessent said in the statement.

"Treasury will not tolerate any support to the regime and will continue to identify, expose, and isolate ⁠Iran’s enablers."

Bessent warned last week that President Donald Trump's administration would sanction a large ​bank as it continues to apply economic ​pressure on Tehran to end a more than six-month U.S. ⁠conflict ‌with ‌Iran.

The U.S. has ⁠imposed a range ‌of economic measures against Iran since the ​conflict began in ⁠February, targeting oil exports, shipping ⁠networks, weapons procurement channels, financial intermediaries, digital ⁠asset ​exchanges and aviation links.
