On June 17 two US officials said Washington and Tehran remotely signed a memorandum intended to end the war and reopen the Strait of Hormuz; the agreement is now in effect. One official said President Trump personally signed the document; the signing had been scheduled for June 19 in Switzerland but was expedited. A mediator’s diplomat and another source said parties discussed accelerating the timeline to open the strait; Iran requested the text remain confidential until the formal signing, and a source denied the White House advanced the timing for political reasons. Delegations led by US Vice President Vance and Iranian parliament speaker Ghalibaf are still expected to meet in Switzerland on June 19.
