According to the government's press office, cited by the TASR news agency, Fico told Merz that he would send an open letter on Tuesday to European Commission President Ursula von der Leyen and circulate it to all EU prime ministers and heads of state, in which he would express concerns relayed to him following a meeting with U.S. President Trump at the weekend and offer solutions.

"I have proposed several solutions to the Federal Chancellor, and I hope that he will visit Slovakia soon, as he promised. We have something to talk about," Fico said. He added that several hundred German companies operate in Slovakia and that the Slovak economy is particularly dependent on German economic development because of the high concentration of car production.

Fico said he and Merz discussed the current "serious international situation," including the escalating transatlantic tensions over the future of Greenland, and the ongoing conflict in Ukraine. He told the German chancellor about his conversation over the weekend with U.S. President Donald Trump and U.S. Secretary of State Marco Rubio at Trump's Mar-a-Lago estate in Palm Beach, Florida.

"The U.S. president is clearly pursuing the nation-state interests of the U.S. If the EU had acted this way, we would be in a completely different place than we are now," Fico said, again arguing that the European Union is not taken seriously on the world stage.

The Slovak government described the Fico-Trump meeting as informal and a sign of respect and trust. The talks covered the war in Ukraine, the European Union, and bilateral relations, and were attended by U.S. and Slovak foreign ministers Marco Rubio and Juraj Blanár.

On Ukraine, Fico said he reiterated his long-held positions to the American president. "All my positions are well-known, and I repeat them in the same wording at every meeting," he said, declaring "Slovakia's peaceful position and the opinion that diplomacy and mutual listening must take precedence over military solutions."

According to Fico, he and Trump shared the view of the European Union as "an institution in deep crisis" in relation to its competitiveness as well as its energy and migration policies. They also discussed an intergovernmental agreement on cooperation in nuclear energy, ceremonially signed in Washington before the Florida meeting. "Both countries are fully aware that solving serious energy challenges is not possible through wind turbines or photovoltaics, but that the basis for the future is the rapid development of nuclear energy," Fico said.
