Ukrainian President Volodymyr Zelensky said on August 12, 2025, that Ukraine would not withdraw its forces from the parts of the Donbas it still controlled as part of a proposed arrangement to stop the war, arguing that abandoning fortified positions could leave the country more vulnerable to future Russian offensives.
His remarks came three days before U.S. President Donald Trump was due to meet Russian President Vladimir Putin in Alaska on August 15. Trump had publicly raised the possibility that a settlement could involve territorial exchanges, while Kyiv and several European governments were seeking assurances that decisions about Ukrainian territory would not be made without Ukraine's participation.
Zelensky Rejects Withdrawal From Ukrainian-Held Donbas
Speaking to reporters, Zelensky said Ukraine controlled roughly 30% of the Donetsk region at the time and had built important defensive positions there. He argued that withdrawing from those areas before a broader security settlement would create opportunities for further Russian advances toward other parts of Ukraine.
According to Reuters reporting from August 12, 2025, Zelensky said territorial questions should be discussed only after a ceasefire and with Ukraine directly involved in negotiations. He also argued that territorial arrangements could not be separated from credible security guarantees.
The Donbas consists of Ukraine's Donetsk and Luhansk regions. Russia and Russian-backed forces had controlled parts of the region since 2014, and Moscow launched its full-scale invasion of Ukraine in February 2022. By August 2025, Russia controlled almost all of Luhansk and most of Donetsk, although exact front-line control remained fluid and estimates varied by source.
Russia also claimed to have annexed Donetsk, Luhansk, Zaporizhzhia and Kherson in 2022, in addition to Crimea, which it annexed in 2014. Ukraine and most United Nations member states did not recognize those territorial claims.
Russian Advance Near Dobropillia Raises Pressure Before Summit
The diplomatic dispute unfolded as Russian forces made a sudden push near Dobropillia in eastern Ukraine. Ukrainian and independent battlefield reporting indicated that Russian troops penetrated approximately 10 to 17 kilometers in some areas, using small mobile groups to exploit gaps in Ukrainian defenses.
Reuters reported at the time that the advance was serious but did not amount to a broad collapse of the Ukrainian front. Ukrainian officials said forces were moving to contain the infiltrating units, while military analysts cautioned that it was not yet clear whether Russia could consolidate all of the territory its troops had entered.
Zelensky acknowledged Russian movement in several locations but said Ukrainian forces were preparing countermeasures. He also characterized the timing of the advance as an attempt by Moscow to strengthen the impression that Russia was gaining momentum ahead of Putin's meeting with Trump. That interpretation represented Kyiv's assessment of Russian intent rather than an independently established fact.
Zelensky also said Ukrainian intelligence indicated Russia was preparing additional offensive activity in the Zaporizhzhia, Pokrovsk and Novopavlivka sectors. Battlefield claims from either side remained difficult to verify in real time.
What Was at Stake in the Alaska Meeting
No publicly agreed peace framework existed before the Alaska summit, and detailed Russian and U.S. negotiating positions had not been formally published. Trump described the meeting as an opportunity to assess whether progress toward ending the war was possible rather than guaranteeing an immediate agreement.
Kyiv was particularly concerned about Trump's references to territorial exchanges. Russia controlled about 19% of internationally recognized Ukrainian territory in August 2025, according to Reuters' territorial assessment, including Crimea and extensive areas in eastern and southern Ukraine.
Zelensky said agreements concerning Ukraine's territory should not be negotiated without Ukrainian participation. He also referred to Ukraine's constitutional framework, under which changes to the country's territory are subject to a nationwide referendum rather than unilateral presidential action.
European governments and NATO leaders likewise argued publicly that Ukraine should participate in decisions affecting its sovereignty and security, while opposing legal recognition of Russian territorial claims imposed through force.
The Summit Did Not End the War
Trump and Putin ultimately met at Joint Base Elmendorf-Richardson in Anchorage on August 15, 2025. The meeting did not produce a ceasefire or final peace settlement. Trump subsequently met Zelensky and several European leaders at the White House on August 18 as diplomacy continued over possible negotiations and security arrangements.
The war continued well beyond those meetings. By September 2026, diplomatic efforts were still unresolved, and Russia continued seeking control of the remaining Ukrainian-held parts of Donetsk while Ukraine continued resisting territorial concessions demanded by Moscow.
Later Battlefield Developments
The Russian breakthrough near Dobropillia in August 2025 did not develop into the decisive collapse of Ukrainian defenses that some observers initially feared. Ukrainian forces later counterattacked in the sector, and Ukraine's military chief said in September 2025 that Russian spring and summer offensives had failed to achieve their major strategic objectives.
The front nevertheless remained highly contested. In September 2026, Russia was still pressing Ukrainian defenses in Donetsk, particularly around the approaches to Sloviansk, Kramatorsk and other fortified eastern positions.
Ukraine, meanwhile, reported fresh counteroffensive gains. On September 30, 2026, Zelensky visited an eastern military command post and said Ukrainian forces had regained about 176 square kilometers during an operation aimed at disrupting Russian efforts to break through toward the Sloviansk-Kramatorsk area. Battlefield figures provided by either side remain subject to change and are not always independently verifiable in full.
Territory Remains Central to Peace Negotiations
More than a year after the Alaska summit, the territorial question that prompted Zelensky's August 2025 warning remained one of the central barriers to a settlement. Russia continued to seek the remaining Ukrainian-held territory in Donetsk, while Kyiv maintained that it would not simply withdraw from strategically important positions as a condition imposed before a durable agreement.
U.S.-led diplomatic efforts also continued. In September 2026, American officials were working on proposals for renewed trilateral talks involving the United States, Ukraine and Russia, but no comprehensive settlement had been reached.
The original dispute therefore proved broader than a single proposed territorial exchange. It concerned the sequencing of a ceasefire, Ukraine's role in negotiations over its territory, the security consequences of abandoning fortified ground, Russia's continuing territorial objectives and the guarantees that would be required for any lasting political settlement.
