Update(1500ET): Shortly before the afternoon press briefing, the White House belatedly issued its call readout summary. The Chinese side had called for direct talks between NATO and Moscow to solve the Ukraine crisis, while the fresh White House readout says Biden warned Xi over the "implications and consequences if China provides material support to Russia as it conducts brutal attacks against Ukrainian cities and civilians."

Here's the full White House text below:

President Joseph R. Biden, Jr. spoke today with President Xi Jinping of the People's Republic of China (PRC). The conversation focused on Russia's unprovoked invasion of Ukraine. President Biden outlined the views of the United States and our Allies and partners on this crisis. President Biden detailed our efforts to prevent and then respond to the invasion, including by imposing costs on Russia. He described the implications and consequences if China provides material support to Russia as it conducts brutal attacks against Ukrainian cities and civilians. The President underscored his support for a diplomatic resolution to the crisis. The two leaders also agreed on the importance of maintaining open lines of communication, to manage the competition between our two countries. The President reiterated that U.S. policy on Taiwan has not changed, and emphasized that the United States continues to oppose any unilateral changes to the status quo. The two leaders tasked their teams to follow up on today's conversation in the critical period ahead.
