United States President Donald Trump has cautioned China and Russia against supplying weapons to Iran, warning that such a decision would be “very bad for them” and “certainly not in their best interests.”

In a statement shared on his Truth Social platform, Trump disclosed that Chinese President Xi Jinping assured him during their recent meeting in Beijing that China would not provide or sell weapons to Iran.

“President Xi, at our recent meeting in Beijing, China, told me that he would not, under any circumstances, give or sell Weapons to the Islamic Republic of Iran — And that statement included Chinese Companies,” Trump wrote.

“Considering our relationship, I take him at his word and, besides, I am doing him very big favors, also.”

The U.S. president said Russian President Vladimir Putin also gave him similar assurances despite the ongoing conflict in Ukraine.

“Likewise, President Putin, despite the horrible War going on in Ukraine (The relationship remains, as it does with President Zelenskyy), told me that he would not sell Weapons to Iran.”

Trump maintained that the United States does not sell weapons directly to Ukraine but instead supplies them to NATO member countries.

“He understands that I do not sell Weapons to Ukraine, but to NATO Countries. They pay full price, and how those Weapons are distributed, I have no idea,” he said.

According to Trump, the assurances from both leaders convinced him that neither China nor Russia was currently providing military support to Iran.

“Therefore, two major Countries that people speak of often in terms of Iran are, in my opinion, not participating.”

He, however, warned that any future decision by either nation to arm Iran would attract serious consequences.

“If they did, it would be very bad for them. Certainly not in their best interests.”

Trump ended the statement by saying, “Thank you for your attention to this matter!”
His remarks come amid escalating tensions between Washington and Tehran.

Earlier, U.S. Secretary of State Marco Rubio issued one of the administration’s strongest warnings yet to Iran while speaking to journalists after the Association of Southeast Asian Nations (ASEAN) Foreign Ministers’ Meeting in the Philippines.

Rubio said President Trump’s approach goes beyond the traditional “an eye for an eye” principle.

“I saw [Abbas] Araghchi, their foreign minister, who the other day said something about their policies, ‘an eye for an eye.’ The president’s policy is a head for an eye,” Rubio said.

“I mean, honestly, that’s what it’s going to be. I mean, they will pay a very heavy price.”
He further claimed that recent U.S. military operations had significantly weakened Iran’s military capabilities.

“They’re going to continue to pay a very heavy price. Their industrial base has been decimated. Their defense industrial base has been decimated to losing launchers, losing radars every single night.”

Rubio’s comments followed another warning from Trump on Wednesday, in which he threatened direct military action if commercial ships in the Strait of Hormuz were attacked again.

“From this point forward, any time the Islamic Republic of Iran shoots at a ship in the Strait of Hormuz, whether it be by Missile, Rocket, Drone, or any other device or weapon, the United States will bomb and destroy ONE BRIDGE OR POWER PLANT, including those located next to, or in, the Capital City of Tehran,” Trump wrote.

The latest statements highlight Washington’s increasingly hardline stance toward Iran, with the Trump administration signalling that any further attacks on international shipping or U.S.
