Tehran said on Tuesday that its intent is to maintain control over the vital Strait of Hormuz, a crucial question in the Middle East war talks with Washington that just wrapped up in Switzerland.

Vice President JD Vance called the negotiations a “very good foundation” for a final deal to end the conflict, noting on Monday that Washington suspended sanctions on Iranian oil.

But critical questions like Iran’s nuclear programme and Hormuz, a major conduit for the world’s oil supply, have not been resolved despite an initial deal between Washington and Tehran.

Technical talks that followed higher-level negotiations in Switzerland have concluded, with working groups to be set up on nuclear issues and sanctions, Iran’s state media reported Tuesday.
