U.S. Treasury Secretary Janet Yellen on April 16 warned that the United States intends to hit Iran with new sanctions over its unprecedented attack on Israel, and these actions could seek to reduce Iran's capacity to export oil.
"I fully expect that we will take additional sanctions action against Iran in the coming days," Yellen told a news conference in Washington.
The United States has taken previous action to contain Iran's "destabilizing" behavior by diminishing its ability to export oil, she said.
"Clearly, Iran is continuing to export some oil. There may be more that we could do."
The United States and its Group of Seven (G7) allies are continuing to explore a range of possibilities to unlock the value of nearly $300 billion in frozen Russian assets to aid Ukraine, U.S. Treasury Secretary Janet Yellen said on April 16.
She said Ukraine needed ongoing streams of support, and that is driving the quest to monetize the frozen Russian assets.
She also said the United States and the G7 were absolutely committed to Ukraine's support and urged Congress to approve military aid, calling it "a humanitarian and moral imperative."
