China offers to mediate in Ukraine after Zelensky's call with Xi.

Ukraine's President Zelenskyy sees an "opportunity" in China's offer to mediate with Russia, but stresses "territorial integrity" and the importance of observing key security rules, particularly in terms of the inadmissibility of threats of the use of nuclear weapons. China's leader Xi Jinping promised to send an envoy to Kyiv to discuss a "political solution," raising the prospect of China acting as a potential peacemaker in Russia's war on Ukraine. However, both sides appear to be bracing for what's to come, with few expecting an easing of the bloodshed.
