U.S. President Donald Trump has declared that the Iranian side's proposed terms for an end-of-war agreement are "completely unacceptable." This reaction comes as both sides remain at odds over Iran's nuclear program—a core issue in the negotiations—while Iran has refused to yield on its demands for war reparations and control over the Strait of Hormuz. Although both parties are maintaining the ceasefire, attention is turning to whether China will step in as a mediator after the U.S.-China summit set to begin on the 14th.
On the 10th (local time), President Trump wrote on his social media platform, Truth Social, "I just read the response from Iran's so-called 'representatives.' I don't like it. It's completely unacceptable." He revealed that Iran had submitted its response to the U.S.-proposed end-of-war agreement via Pakistan, which is acting as an intermediary.
President Trump did not disclose the specific details of Iran's response but expressed strong dissatisfaction with Iran. In another post on social media, he said, "For 47 years, Iran has been playing games with the United States and the rest of the world. Iran has killed Americans with bombs and, most recently, wiped out 42,000 innocent protesters, mocking the United States. But they will laugh no more," he warned.
Israeli Prime Minister Benjamin Netanyahu, who spoke with President Trump by phone on the same day, also emphasized that the war would not end before the Iranian nuclear issue is resolved. In an interview with CBS, Netanyahu stated, "There is still uranium and nuclear facilities in Iran, so there is work left to do. All highly enriched uranium must be removed from Iran, and all of Iran's uranium enrichment facilities must be dismantled."
Analysts say that the two sides failed to bridge their differences over Iran's nuclear abandonment—a key sticking point—resulting in a lack of breakthrough in the negotiations. Citing sources involved in the talks, The Wall Street Journal (WSJ) reported, "The United States demanded that Iran limit uranium enrichment for 20 years, but Iran continues to seek a shorter period and has refused to dismantle its nuclear facilities. Iran proposed diluting some of its highly enriched uranium and transferring the rest to a third country, while also demanding guarantees that the uranium would be returned if the U.S. were to renege on the agreement in the future."
However, some within the Trump administration are discussing the possibility of a provisional end-of-war agreement that temporarily sets aside the Iranian nuclear issue. In an interview with NBC, U.S. Secretary of Energy Chris Wright responded to a question about the feasibility of a provisional agreement that does not resolve all issues related to Iran's nuclear program by saying, "There is definitely a possibility." He added, "But the Trump administration's top priority is to end Iran's nuclear program."
Iran is also maintaining a hardline stance by demanding war reparations. The Iranian government stated on state broadcaster IRIB, "We have delivered our response to the U.S. proposal to Pakistan, which is acting as an intermediary, and we have demanded war reparations from the United States and recognition of our sovereignty over the Strait of Hormuz." The statement continued, "We reject any measures that could weaken our control over this strategic maritime passage."
The Iranian Revolutionary Guard also issued a strong response to Trump's statements. According to Iranian news agency Tasnim, an official from the Revolutionary Guard said, "No one in Iran is planning anything to please Trump. His reaction does not matter at all," adding, "Any negotiation plan must consider only the interests of the Iranian people."
According to Tasnim, in addition to war reparations and control over the Strait of Hormuz, Iran's core demands include an end to the U.S. naval blockade and a 30-day lifting of the ban on Iranian oil sales. Iran is also insisting that nuclear issues such as enriched uranium be excluded from the end-of-war agreement.
With President Trump scheduled to visit China on the 13th, he will meet with Chinese President Xi Jinping without having reached an end-of-war agreement beforehand. As a result, there are growing expectations that the U.S. may pressure China to mediate the negotiations during the summit with Xi set for the 14th.
The Iranian side is also calling on China to act as a mediator for an end-of-war agreement with the United States. Abdolreza Rahman Fazli, Iran's ambassador to China, wrote on the social media platform X, "Any potential agreement must be accompanied by guarantees from major powers. Given China's status with Iran and other Persian Gulf countries, China can serve as a guarantor for any agreement."
