Refinitiv reported a senior U.S. official on Wednesday read a 14-point
memorandum due to be signed in Switzerland on Friday, saying it is not a final,
binding agreement and either side may withdraw. The official said the next
negotiation phase will focus on sequencing and implementation of measures in the
preliminary pact and described the Swiss meeting as critical to whether the
memorandum can evolve into a comprehensive agreement. He said the text he read
largely matches versions previously leaked to the media.
