Donald Trump previously announced direct negotiations with the Iranian side at "almost the highest level" this Saturday, which Tehran later corrected.
Iran has previously ruled out direct talks with the US under threats and pressure, but has left the door open for indirect negotiations.
"It is as much an opportunity as it is a test. The ball is in America's court," the minister said on X.
Meanwhile, Russian Foreign Ministry spokeswoman Maria Zakharova said that Russia, China and Iran will hold talks on Iran's nuclear program in Moscow tomorrow.
