Russian President Vladimir Putin has again told US officials that Russia can capture Ukraine’s Donetsk Oblast within several months, according to Ukrainian President Volodymyr Zelenskyy.

Speaking to the UN General Assembly on 24 September, Zelenskyy said this was the latest in a long series of similar promises as Russia has spent nearly five years trying to seize the region. He said Putin has made such promises 17 or 18 times, repeatedly pushing the deadline further back.

He contrasted those promises with Russia’s heavy battlefield losses and relatively limited territorial gains.

Russia has paid a huge price for its Donetsk offensive

Zelenskyy said Russian forces suffered 248,964 troops killed or severely wounded between January and August 2026.

He said Russia had captured only slightly more than 1,000 square kilometers of Ukrainian territory this year, while Ukraine had already liberated a significant portion of those gains.

Zelenskyy presented the figures as the human cost of Putin’s continued attempt to seize Donetsk, arguing that Russia is paying an enormous price for relatively limited territorial gains.

“Always the same: ‘Just a few more months,’” Zelenskyy said, adding that Putin would again fail to meet his latest deadline.

The Russian offensive is also facing a recent setback in northern Donetsk. Ukraine launched Operation Vivaldi in September to clear Russian infiltrators and retake ground near Lyman, disrupting Russia’s plan to encircle the fortified cities of the Donetsk “Fortress Belt.”

Ukrainian forces have reported retaking several settlements and clearing up to 125 square kilometers in the operation, although the full scope of the offensive remains undisclosed.

Zelenskyy also warned that Russia’s ambitions extend beyond Donetsk. After saying Putin would again fail to capture the region, he said Russia would continue seeking other Ukrainian cities, naming Odesa, Kharkiv and Dnipro, while also pointing to Russian pressure on Moldova and threats toward Poland and the Baltic states.

Russia continues to pour missiles and drones into Ukraine

The battlefield campaign has been accompanied by a sustained Russian long-range attack campaign against Ukrainian cities and infrastructure.

Since the beginning of 2026, Russia has launched more than 2,100 missiles against Ukraine, including more than 950 ballistic missiles, according to Zelenskyy.

Ballistic missiles are particularly difficult for Ukraine to counter because it has a limited supply of interceptors capable of engaging them. Russia’s heavy use of ballistic weapons is therefore contributing directly to civilian deaths and infrastructure destruction.

Over the first eight months of the year, Russia also used 63,000 attack drones of various types, Zelenskyy said. More than 7,700 were jet-powered Geran drones, which he described as particularly destructive and dangerous.

The newer jet-powered drones are faster and more advanced than earlier Shahed-type models, making them harder to intercept and adding to the pressure on Ukraine’s air defenses as Russia attacks cities and infrastructure.

Zelenskyy said Russia was using the drones continuously to disrupt economic activity and normal life in Ukrainian cities, including by making it harder for children to attend school.

The figures show the scale of the Russian campaign beyond the front line. Alongside its ground offensive, Russia is using sustained missile and drone strikes to kill civilians, destroy infrastructure, and exhaust Ukraine’s air-defense resources.

North Korean troops add to Russia’s war effort

Zelenskyy also highlighted North Korea’s direct involvement in Russia’s war, saying its troops have suffered heavy losses while gaining battlefield experience alongside Russian forces.

He said North Korea’s military capabilities were also benefiting from its cooperation with Russia, pointing to improvements in its ballistic missiles and drone capabilities.

Ukraine recently transferred two North Korean prisoners of war to South Korea. Zelenskyy said capturing the soldiers alive had been difficult and described one prisoner’s attempt to take his own life after realizing he was about to be captured.

He said the soldiers had been conditioned to believe they had to die rather than surrender.

“Do you really want to give such a force more time to learn how to fight?” Zelenskyy asked.

Zelenskyy calls for de-escalation before winter

Zelenskyy separately warned that Russia could again target Ukraine’s energy and heating infrastructure this winter.

Russia has already intensified attacks on Ukraine’s energy system ahead of the cold season.

Russia has also explicitly threatened to “freeze” Ukraine this winter, with its Defense Ministry linking the threat to attacks on Ukrainian infrastructure. The country spent much of the previous winter dealing with the consequences of Russian strikes on power and heating infrastructure, including blackouts and disruptions to heat supplies.

Zelenskyy said Ukraine expects the coming winter to be difficult but warned that if Russia continues attacking Ukraine’s energy and heating systems, Ukraine will make the winter painful for Russia as well.

He called for steps toward de-escalation before winter, saying that diplomacy and military strength were both needed to end the war.

Ukrainian President Volodymyr Zelenskyy has used the UN General Assembly in New York to court partners outside Ukraine's NATO core, pitching air-defense cooperation with Japan and drone cooperation with Chile, Ukrainska Pravda reported. In a single day of bilateral talks, he met Japan's Prime Minister Sanae Takaichi, Chile's President José Antonio Kast, and UK Prime Minister Andy Burnham.

The meetings turned on shielding civilian infrastructure before winter and trading Ukraine's battlefield-tested technology for capabilities it still needs. More than four years into Russia's war, a nation that entered the war reliant on donated arms now iterates drones faster than many of its Western backers, and that expertise has become leverage in its own diplomacy.

Zelenskyy pitches Ukraine's know-how for Japan's air-defense tech

In their first summit meeting, Zelenskyy cast the relationship as a two-way exchange.

"Ukraine is ready to share its experience and technologies on a mutually beneficial basis," he said.

While Japan has advanced technologies for protecting lives, particularly in air defense, that could carry Ukraine through the winter if Russia again rejects talks, the President's Office reported.

Ukraine walks into winter with two air-defense problems. It is still testing home-built interceptors to catch Russia's jet-powered drones. And it does not have enough Patriot interceptors to stop ballistic missiles over its cities. Japan holds the key to the second one.

Mitsubishi Heavy Industries runs the only plant outside the US licensed to assemble the PAC-3, the advanced Patriot interceptor. Japan is also the sole maker of the guidance gyroscopes inside older PAC-2 missiles. It has already shipped Japanese-made PAC-3s to the US to refill stocks drained by transfers to Ukraine, and Zelenskyy has floated Mitsubishi as the model for Ukraine's own Patriot line.

The exchange runs both ways. Russia keeps pressing Japan over the Kuril Islands the Soviet Union seized in 1945. Against that backdrop, Ukraine's combat-tested drones could appeal to Tokyo. Kyiv offers the drone know-how it now leads in, and asks for the air-defense edge Japan already has.

Zelenskyy also thanked Tokyo for its sanctions on Russia, energy packages, and humanitarian projects, and Takaichi assured him of continued support. Zelenskyy invited her to Ukraine, including the Kyiv-Pechersk Lavra, which Japan helped restore after a Russian drone strike in June.

Chile opens a door to Latin America

With Kast, Zelenskyy discussed deepening security and drone-technology ties and thanked Chile for backing Ukraine at international forums and for helping return Ukrainian children abducted by Russia. He welcomed Santiago's willingness to help expand Ukraine's presence across Latin America, calling it an opening for "even more promising opportunities," and invited Kast to visit.

Building on ties already in place

Both partnerships rest on existing ground. Japan, barred by its own laws from sending lethal weapons, has delivered generators, transformers, and non-lethal gear, pledged a $6 billion package for 2026, and agreed to help rebuild the Lavra through UNESCO. Talks in Tokyo in July recast Ukraine as a security partner rather than an aid recipient.

Chile joined the coalition to bring abducted Ukrainian children home and, in an April call, heard Zelenskyy float a security arrangement modeled on Ukraine's Gulf-state pacts. The outreach tracks Kyiv's drive to turn its wartime industry into an export business under its "Drone Deals" framework.
