US President Donald Trump on Monday urged Russian President Vladimir Putin to focus on ending the war in Ukraine instead of testing new missiles. Speaking to reporters on board Air Force One during his Asia tour, Trump said that Russia’s latest missile test was “not appropriate.”

"He ought to get the war (in Ukraine) ended. A war that should have taken one week is now in its fourth year. That's what he ought to do instead of testing missiles," Trump said.

His comments came soon after Russia announced the successful test of its nuclear-powered Burevestnik cruise missile, a nuclear-capable weapon that Moscow claims can penetrate any defence system.

Russian President Vladimir Putin said that the country would now move towards deploying this weapon.

According to Russia, the 9M730 Burevestnik, also called "Storm Petrel" and known to NATO as SSC-X-9 Skyfall, is "invincible" to both current and future missile defences, with an almost unlimited range and an unpredictable flight path.

"It is a unique ware which nobody else in the world has," Putin said, dressed in camouflage fatigues during a meeting with generals overseeing the war in Ukraine, in remarks released by the Kremlin on Sunday, local time.

"We need to determine the possible uses and begin preparing the infrastructure for deploying these weapons to our armed forces."

Russia’s Chief of the General Staff, Valery Gerasimov, told Putin that the missile had travelled 14,000 kilometres and stayed in the air for about 15 hours during its test on October 21.

Since first introducing the project in 2018, Putin has described the Burevestnik missile as a response to the United States’ decision to build a missile defence shield after it withdrew from the 1972 Anti-Ballistic Missile Treaty in 2001.

Putin said that Russian specialists once told him that this weapon might never be possible, but now, he said, its "crucial testing" had been completed.

The Russian president added that this test sent a message to the world that Russia would never give in to pressure from the West over the war in Ukraine. The White House has not yet commented on the missile test.

For Trump, who has often described Russia as a "paper tiger" for not being able to take control of Ukraine quickly, the missile test serves as a reminder that Moscow remains a strong global military power, especially when it comes to nuclear weapons.

Putin’s message to the West, after the United States gave Ukraine intelligence on long-range energy targets inside Russia, is that Moscow can strike back if it chooses to.

Last week, Mr Putin said that if Russia were attacked, the response would be "very serious, if not overwhelming." Kremlin spokesperson Dmitry Peskov repeated this message on Russian state television in remarks aired on Sunday, local time.

General Gerasimov said that the Burevestnik missile had flown using nuclear power and that this test was different because it travelled such a long distance, although its range was essentially unlimited.

On Wednesday, Mr Putin also oversaw a large-scale test of Russia’s strategic nuclear forces on land, sea, and air to check their readiness and command systems. During that drill, General Gerasimov said that Yars and Sineva intercontinental ballistic missiles were launched successfully, along with two Kh-102 air-launched cruise missiles.

"The so-called modernity of our nuclear deterrent forces is at the highest level … higher than any other nuclear power," Putin said.

In August 2025, Trump had tried to bring Putin to the negotiating table to end the Ukraine war, which is now in its fourth year. The two leaders met in Alaska for a summit that Trump called “successful.”

However, weeks after that meeting, Russia once again stepped up its attacks on Ukraine, leaving Trump frustrated. Since then, he has issued several warnings and ultimatums to Moscow, Putin, and Russia’s trading partners in an effort to push for a ceasefire.

In his latest move, the United States announced new sanctions on two major Russian oil companies, Rosneft and Lukoil. Before leaving for his Asia tour, Trump said he would not meet Putin again until there was real progress toward a peace deal to end the war.

"I'm going to have to know that we're going to make a deal. I'm not going to be wasting my time," Trump said on Sunday.

"I've always had a great relationship with Vladimir Putin, but this has been very disappointing," he added.
