Japan foreign minister MOTEGI and Iranian foreign minister Araghchi held a 20-minute phone call at 16:30 Beijing time on Sept. 8, the Japanese foreign ministry said. MOTEGI voiced serious concern over a renewed escalation in U.S.-Iran military tensions, urged urgent de-escalation and a resumption of U.S.-Iran dialogue, and pressed Iran to show maximum flexibility. On the Strait of Hormuz, Japan said future management should be discussed under international law by coastal states, strait users and the IMO. MOTEGI also stressed the need to ensure stability in the Bab al-Mandeb, said Japan would cooperate with the Yemeni government, and called on Iran to exert strong influence on the Houthi to exercise restraint. Araghchi outlined Iran’s position.

Ross Harrison, senior fellow at the Middle East Institute, says the US‑Iran standoff is unlikely to shift to a diplomatic resolution while both sides believe coercion yields greater gains than talks. He characterizes current interactions as a 'negotiation on the battlefield' and says true diplomacy requires both sides to conclude that sitting down would produce better outcomes than continued pressure. Harrison adds Iran has sought to honor conditions in a memorandum and treats that document as a key leverage point, while Washington has tried to weaken or strip that leverage. He says the US is now leaning toward economic rather than military pressure; Tehran is pushing back to avoid being sidelined and may escalate to escape what it sees as a trap set by Trump. Unless the ground situation changes in the next day or two, Harrison says he does not see a genuine negotiation channel opening.
