[Mediator Believes U.S.-Iran Negotiations Have Made Little Progress, Iran Insists on Core Demands Unchanged] According to a report by Jinse Finance on May 20, citing The Wall Street Journal and U.S. officials familiar with the relevant terms, Iran's stance in negotiations with the United States to end the conflict has not significantly changed compared to previous rounds that failed to make progress. This has raised doubts about whether an "exit" to the conflict can be found. The mediator pointed out that Iran still insists on its core demands, including ending hostilities, obtaining economic relief, compensation for war damages, and playing a supervisory role in the strategic waterway of the Strait of Hormuz. Additionally, there remain significant differences with the U.S. on the issue of shutting down or long-term suspension of its nuclear program. Regional sources have indicated that the U.S. and Israel have been preparing for a new round of strikes against Iran in the coming days, with some suggesting that an attack could be launched as early as next week.
