On December 28, 2025, the Kremlin announced that Russian President Vladimir Putin and former U.S. President Donald Trump jointly rejected a European-Ukrainian initiative to implement a temporary ceasefire amid the ongoing conflict in Ukraine. The two leaders cautioned that this proposal risks extending the conflict rather than resolving it. Their unified stance intensifies pressure on Kyiv to clarify its position on the contested Donbas region, where fighting remains fierce.

Putin and Trump Reject Temporary Ceasefire in Ukraine Conflict

Kremlin foreign policy aide Yuri Ushakov disclosed that a 75-minute phone call took place between Putin and Trump at the former president’s request, preceding Trump’s scheduled meeting with Ukrainian President Volodymyr Zelenskiy in Miami. The conversation reinforced their shared view that the proposed ceasefire, framed by Europeans and Ukrainians as a step toward a referendum or diplomatic initiative, would likely delay peace and risk renewed fighting.

Ushakov stated, “The presidents of Russia and the United States hold similar views that the temporary ceasefire option proposed under the pretext of preparing a referendum only leads to prolonging the conflict and is fraught with renewed hostilities.” He emphasized the need for Kyiv to make a “bold decision” in line with Russian-U.S. discussions centered on the Donbas area.

Geopolitical and Territorial Dynamics

Russia currently exercises control over approximately 90% of the Donbas region, equating to about 20% of Ukraine’s total territory. Ukrainian forces retain the remaining 10% of Donbas. Moscow demands that Ukraine withdraws from this territory as a prerequisite for any peaceful resolution. This territorial control remains a core sticking point in ongoing negotiations.

Donald Trump, positioning himself as a peace mediator, has previously pledged to end Europe’s deadliest conflict since World War II. His envoy, Steve Witkoff, along with son-in-law Jared Kushner, has engaged with officials from Russia, Ukraine, and Europe to explore diplomatic options. Nonetheless, European and Ukrainian leaders express suspicion that Trump’s approach could marginalize Ukraine politically while European allies shoulder economic reconstruction costs.

Ushakov noted Trump “listened attentively to Russian assessments of the real prospects for reaching an agreement,” while continuing to push for a swift end to hostilities. Trump also highlighted potential economic cooperation among the United States, Russia, and Ukraine contingent upon peace.

Conflict: Market and Diplomatic Outlook

With the rejection of the European-Ukrainian ceasefire by Putin and Trump, the conflict remains unresolved, sustaining significant geopolitical uncertainty. The persistent territorial dispute over Donbas and surrounding regions continues to hamper diplomatic breakthroughs.

The ongoing fighting affects global markets, particularly energy and commodities, due to Russia’s significant role as a major supplier. In 2025, Russian forces reportedly advanced 12 to 17 square kilometers monthly, maintaining the conflict’s intensity despite numerous negotiation attempts.

Investors and policymakers should expect sustained volatility driven by developments in Kyiv’s decisions and international diplomatic initiatives. The protracted conflict will keep its imprint on economic cooperation and market stability in the near term.
