The Ukrainian president says Monday's talks have been "constructive" as European leaders repeat calls for a ceasefire.

U.S. President Donald Trump says he has called Russian President Vladimir Putin and begun to arrange a meeting between Putin and Ukrainian President Volodymyr Zelenskyy, a critical step toward bringing a possible end to Russia's war on Ukraine.

Russian Foreign Minister Sergei Lavrov said on Tuesday that it was clear at Friday's U.S.-Russia Alaska summit that U.S. President Donald Trump and his team sincerely wanted to achieve a long-term and sustainable peace in Ukraine.

For years, Donald Trump criticized presidents for empty threats. He often pointed to then-President Barack Obama failing to enforce his “red line” on Syria using chemical weapons. During his first term in 2017, Trump called it a “blank threat” that cost us “in many other parts of the world.”

President Donald Trump said on social media Saturday that a deal better than “a mere Ceasefire” is in the works with Vladimir Putin, hours after Trump’s high-stakes summit with the Russian leader in Alaska failed to produce an agreement to halt Russia’s invasion of Ukraine.

Former Russian President Dmitry Medvedev said on Tuesday that European leaders had failed to outplay Donald Trump, but that it was unclear how Ukrainian President Volodymyr Zelenskiy would present the issues of territory and a security guarantee.

White House advisor Peter Navarro criticized India's Russian oil imports in an op-ed after Trump announced new tariffs targeting India and other countries buying Russian energy.

As Trump and the leaders of European countries finished their family photo, the group was preparing to begin the summit in earnest.
