Ukrainian President Volodymyr Zelenskyy said on Saturday that security guarantees for Ukraine will be ready “in the coming days,” following intensified efforts to end Russia’s war on his country.

“At present, the teams of Ukraine, the United States, and European partners are working on their architecture,” Zelenskyy wrote in a post on the social media platform X, after a phone call with Dutch Prime Minister Dick Schoof.

“There is now a real chance to end this war, and Ukraine is ready for constructive steps that can bring true peace closer,” Zelenskyy said in the post.

“However, Russia is showing no intention of peace on its side and continues shelling our cities. We interpret all signals coming from Moscow these days in the same way. Pressure is needed to change their position, as well as a meeting at the highest level to discuss all issues,” the Ukrainian leader added.

Work on the security guarantees accelerated following a gathering of European leaders in the White House last Monday, during which U.S. President Donald Trump said that a bilateral meeting between Zelenskyy and Russian President Vladimir Putin was in the works. But frustrations have grown since then, with Moscow showing reluctance to commit to peace talks.

The Dutch prime minister was due to visit Kyiv on Saturday, but his trip was postponed after a political crisis over sanctions against Israel rocked the country’s caretaker government.
