Asia-Pacific markets fell on Friday as investors assessed the durability of a U.S.-brokered peace agreement with Iran.

U.S. Vice President JD Vance on Thursday defended President Donald Trump's interim agreement with Iran, saying any economic relief for Tehran would depend on the country complying with the terms of the deal.

"The United States isn't giving up a cent of money to Iran," Vance said. "The only way the Iranians get any of these resources ... is if they comply fully" with the terms of the deal.

Iran's Supreme Leader, Ayatollah Mojtaba Khamenei, likewise described the agreement as conditional, saying on Thursday that he approved the memorandum only after receiving guarantees that Iran's rights and the "resistance front" would be safeguarded.
