Ukrainian President Volodymyr Zelenskyy is expected to arrive in the German capital on 15 December, Bild reports.
The German government has not officially confirmed the visit, but unusually high security measures are already being implemented in the government quarter and in the airspace over Berlin.
Members of the Bundestag have been informed about "police measures in connection with a state visit to the Reichstag building and the Chancellor's office" with access restrictions on Monday, according to the publication.
Berlin police notified airports in the Berlin area on Thursday about an upcoming state visit. "In connection with the visit of a person under the highest level of protection, a flight restriction zone will be introduced in Berlin on 15 December 2025 to protect the state guest," the police letter said.
Bild notes that such measures are only taken for state guests under the highest threat level, such as US presidents or the Ukrainian president.
The visit comes amid preparations for a meeting in Berlin focused on a possible ceasefire in Ukraine, scheduled for early next week. German Chancellor Friedrich Merz has invited US representatives to join the meeting.
The invitation followed a tense phone call on Wednesday between Merz, Emmanuel Macron, Keir Starmer, and Donald Trump, during which the parties attempted to bridge differences over the direction of peace efforts. Trump later acknowledged the existence of disputes, saying "quite strong words" were exchanged during the call, highlighting disagreements over the US-supported approach.
Details of further phone calls will be communicated only "after consultation with the parties involved," according to the statement. Bild reports that Merz will hold talks with, among others, US President Donald Trump and Ukrainian President Volodymyr Zelenskyy.
The discussions center primarily on Trump's 28-point plan for Ukraine, which demands tough concessions from the country occupied by Russia but, according to the US president, aims to establish peace.
Part of the plan that raises concerns among European security experts involves Ukraine renouncing disputed territories—territories that Russia has not yet captured. The plan also provides for cutting the Ukrainian army in half and transferring key weapons from the West. The US would also reduce its military support to the invaded country.
In return, Russia, which invaded all of Ukraine in 2022, would halt attacks.
