Iranian Foreign Ministry spokesman Esmaeil Baghaei said on Monday that the recent truce plan proposed by the United States contains "excessive, unrealistic and unreasonable" demands.
At a weekly press conference in Tehran, Baghaei stressed that Iran's stance has been clear from the beginning, and the country has had no direct negotiation with the United States.
"The materials that have been conveyed to us under various titles such as the '15-point plan' mainly include very excessive, unrealistic, and unreasonable demands. The meeting that Pakistan held with its neighboring countries is a framework that they established themselves. We did not participate in this framework. It's a blessed thing that countries in the region are concerned about peace and security. Our stance has been clear. Once we reach a conclusion, we will announce it in an appropriate way, because we have confidence in ourselves, and we know what we want," Baghaei said.
When asked if Iran has a political solution to end the war, Baghaei said the U.S. and Israel have intensified attacks against Iran, attempting to cripple its scientific foundation and cultural heritage, so Iran has to focus on defending itself.
Iran's pursuit for ending the war is clear, he said, adding a decision will be made based on the leadership's opinion if necessary.
On Feb 28, Israel and the United States launched joint attacks on Tehran and several other Iranian cities, killing Iran's Supreme Leader Ali Khamenei, along with senior military commanders and civilians. Iran has responded by launching waves of missile and drone strikes targeting Israel and U.S. bases and assets in the Middle East.
Baghaei reiterated that Iran has never regarded its neighbors as enemies, and as the country has stated repeatedly, its operations only target U.S. military bases in the region.
The U.S. and Israel have been using these bases to attack Iran, which violates international law, Baghaei emphasized, calling on neighboring countries to forbid attacks against Iran from their territories.
Referring to the mass "No Kings" rallies across the U.S., Baghaei said there has been an industry where those who benefit from wars waged by the U.S. attempt to justify them to gain public approval, but these protests indicate this doesn't work anymore.
Americans see no reason to start a war against Iran, and they know the war will plunge the U.S. into a predicament, he said.
Israel and the United States launched waves of airstrikes from Sunday night to Monday noon, with explosions heard across Iran, including in Tabriz and Zanjan in western Iran, and in Kish and Shiraz in the south.
Meanwhile, the Islamic Revolutionary Guard Corps (IRGC) announced it had launched the 87th wave of Operation True Promise 4 on Monday. The IRGC has released a video about the operation, saying it had targeted U.S. and Israeli military sites with missiles and drones.

A full-chain open ecosystem for embodied intelligence has taken initial shape in Beijing, centered on a national-local jointly established innovation platform. The Beijing Humanoid Robot Innovation Center is working to break down technology barriers and data silos by open-sourcing key robotics frameworks and AI models.
After its "Tiangong Ultra" humanoid robot won the world's first humanoid robot half marathon in Beijing last year, the Beijing Humanoid Robot Innovation Center has accelerated efforts to open-source its core technologies, aiming to help the industry move faster toward real-world applications.
In the world's first humanoid robot half-marathon held in April 2025 in Beijing, Tiangong Ultra claimed championship by completing the 21.0975-kilometer race in 2 hours, 40 minutes and 42 seconds. Soon after, the center open-sourced its motion-control framework, followed by the release of multiple embodied AI models, including VLM, VLA and world models.
"First, our technology must be leading and earn everyone's recognition. Second, the technology really has to serve everyone well. Some companies do have good technology, they may do well on one specific aspect, but they don't open-source it, so others can not have access to it. But we are a fully open-source platform. Last year's marathon was a very good application scenario to test the stability and reliability of a robot's hardware. At that time, robots from three companies finished the race. Ours completed the whole race, and we were more than one hour ahead of the second place," said Xiong.
The results, he said, demonstrated that Tiangong's hardware platform and motion-control capabilities are among the industry's leading technologies.
Since the platform was made open-source, the center said its latest technologies have been downloaded more than 2 million times across China.
This year's humanoid robot half-marathon is scheduled for April 19, featuring a more demanding route including urban slopes, undulating roads and ecological sections inside parks.
The upgraded course is expected to pose greater challenges for robots' terrain adaptability and motion-control algorithms.
"This year, we have actually made all of our robots fully open-source and open. Now it is no longer just us that are using Tiangong technology to participate in the competition. Instead, more than 20 universities, research institutes and some enterprises in the industry are competing in the race by equipping the robots with their own algorithms. Some have even made modifications and improvements based on Tiangong, and then joined the competition. This is how the value of our platform is brought into play," said Xiong.
The center announced the launch of an ecosystem development plan for open-source embodied intelligence, which it described as the world's first full-chain ecosystem initiative centered on a national-local joint innovation platform.
The plan aims to break down technology barriers and data silos while linking upstream and downstream segments of the industrial chain.
"The current robots are still far from mature enough if they truly work in real-world situations, like on production lines, in some dangerous scenarios by replacing humans to do some specific work. We need to open-source all these technologies to the industries, so that everyone can use these technologies and improve rapidly, instead of engaging in low-level competition," said Xiong.
China now has more than 100 robotics companies, but many still focus mainly on building robot bodies, while capabilities such as motion performance, environmental perception, task planning and AI decision-making remain relatively weak, Xiong explained.
With open-source platforms and stronger foundational technologies, these companies could shift toward higher-value entry points in the market.
"We hope that the open-source technologies we release can serve as underlying technologies, so that they can innovate in vertical fields. For example, some may be in the power industry, some in the petrochemical industry, some in elderly care, and some in household services. Because the market is actually big enough, so everyone can use its own strengths, its understanding and insights into the industry to achieve better results in that vertical field, rather than doing repetitive work," Xiong noted.
