The decision follows Trump's earlier statement that any country doing business with Iran would face a 25 percent tariff on trade with the United States.
Despite the escalating rhetoric, the White House said diplomacy remains Washington's preferred option.
Press Secretary Karoline Leavitt noted on Monday that while dialogue is favored, the administration is not ruling out military action if circumstances require it.
In a series of posts on his Truth Social platform, Trump urged Iranians to continue protesting and called on them to 'take over your institutions,' condemning what he described as the killing of demonstrators. He claimed that 'help is on the way,' without providing further details.
Trump said the suspension of meetings would remain in place until the 'senseless killing of protesters stops.'
In recent days, he has again raised the possibility of U.S. military strikes, warning that a harsh crackdown by Iranian authorities could trigger a strong response from Washington.
Iranian authorities have, for their part, consistently blamed the United States for stirring instability in the country.
In the latest accusation, Iran's top military commander, Abdolrahim Mousavi, claimed that the US and Israel had sent members of the armed group ISIL (ISIS) into Iran to conduct attacks, though he did not present any evidence to support the claim.
