South Korea's finance minister said the current exchange rate is too high.

On 22 June, Iran's chief negotiator and parliament speaker Ghalibaf said an Iran‑US memorandum of understanding explicitly calls for ending wars against Iran and its allies. He said both sides concluded in Swiss talks that Iran and the United States should jointly guarantee Lebanon's territorial integrity. The MoU already includes assurances on territorial integrity and should be implemented; the parties agreed to establish a coordination center to resolve related issues, enable displaced Lebanese to return and facilitate withdrawal of Israeli forces from Lebanese territory.

June 22 — An Iranian delegation led by parliament speaker Kalibaf left Switzerland and returned to Iran after Kalibaf said he learned of President Trump’s threatening remarks. He told U.S. Vice President Vance at the talks that Iran would not negotiate under threats or coercion; the delegation then suspended talks and did not return. Iran only held follow-up discussions with mediators Pakistan and Qatar and referred to their joint statement later that day. Kalibaf said Iran continues to distrust the United States and considers that distrust reasonable given its position.
