President Trump is warning of "severe consequences" for nations that continue trading with Iran.
It's because they then won't be trading with the United States.
His comment came just as the first round of American sanctions was reimposed on Iran early Tuesday.
YNET News reported Trump called them "the most biting sanctions ever imposed."

"Anyone doing business with Iran will NOT be doing business with the United States," the president said. "In November they ratchet up to yet another level. I am asking for WORLD PEACE, nothing less!"
CBN News reported Israeli Prime Minister Benjamin Netanyahu praised the move.
"This is an important moment for Israel, the US, the region, [and] entire world. It represents the determination to curb Iran's aggression in the region and its ongoing intention to arm itself with nuclear weapons," Netanyahu said.
"I call on the countries of European, which talk about stopping Iran, to join this measure," he said. "The time has come to stop talking and to take action and that is exactly what the US has done and what Europe should do."
In April, Netanayhu made public thousands of documents smuggled out of Iran that revealed the Islamic regime never abandoned its nuclear weapons program.
The revelation showed Iran violated the nuclear deal reached by Barack Obama, which rewarded Tehran by freeing up as much as $150 billion in Iranian assets.
Trump called it a "horrible, one-sided deal that should never, ever been made."
The re-activated sanctions this week came under an executive order signed by President Trump largely aimed at financial transactions, the auto industry and aviation.
Oil and central bank limits are expected in November.
Iran had accused the U.S. of reneging on the nuclear agreement, signed by the Obama administration. But it never was never approved by the Senate as a treaty and got no affirmation outside of the White House, which meant it could be changed or dropped by the current administration without ramifications.
Iranian President Hassan Rouhani said his nation can work with China and Russia on its economy, which has seen its currency drop some 80 percent in value in recent months.
He also wanted "compensation" for decades of American "intervention" in the Islamic Republic.
"Secretary of State Mike Pompeo said sanctions are an important pillar in U.S. policy toward Iran and will remain in place until the Iranian government radically changes course," YNET reported.
