President Joe Biden will tell his Chinese counterpart Xi Jinping that the U.S. will “impose costs” if China backs Russia, in a call to discuss the war planned for 9 a.m. Washington time Friday, Secretary of State Antony Blinken said. Ukrainian officials said Russian strikes on infrastructure and residential areas continued, and in the southern city of Mariupol local authorities described the situation as “critical.” The country’s biggest utility said 1.3 million people were without power. Oil rose after the Kremlin pushed back against reports of progress in peace talks. The U.S. House of Representatives voted to end regular trade relations with Russia, and the Pentagon warned that Russia may become more reliant on its nuclear deterrent as war and sanctions weaken its conventional forces.
