The Kremlin said on Friday that it did not believe that a tougher stance U.S. President Donald Trump has adopted towards Russia over its war in Ukraine means the end of U.S-Russia talks aimed at reviving their battered ties.

U.S. President Donald Trump's decision to ramp up arms shipments to Ukraine is a signal to Kyiv to abandon peace efforts, Russia said on Thursday, vowing it would not accept the "blackmail" of Washington's new sanctions ultimatum.

The European Union approved a new series of sanctions against Russia on Friday in response to its ongoing war in Ukraine. The measures include a lower oil price cap, a ban on transactions involving the Nord Stream gas pipelines,

President Vladimir Putin believes Russia's economy and its military are strong enough to weather any additional Western measures, sources said.

President Trump’s recent commitment to provide more aid to Ukraine could increase pressure on Russia to negotiate an end to the war.
