The next phase of US-Iran talks in Doha depends on Washington implementing the memorandum of understanding it signed with Tehran, an analyst says.

Zohreh Kharazmi, a professor at the University of Tehran, told Al Jazeera she does not expect major progress on the Strait of Hormuz unless the terms of the MoU are carried out by the US.

“The articles of the MoU should be realised to have a step forward. The ball is in the United States’s court,” she said.
