Chinese President Xi Jinping could wade deeper than before into Ukraine diplomacy as soon as next week, staging both his first trip to Russia and his first talks with Ukraine's President Volodymyr Zelenskyy since Moscow's invasion.

Several sources familiar with the plans said Xi could visit Moscow next week, an earlier-than-expected trip in response to a long-standing invitation from President Vladimir Putin. His plans to also hold a video conference with Zelenskyy were reported by the Wall Street Journal, citing sources, which could not be immediately confirmed independently.

The Chinese foreign ministry did not immediately respond to requests for comment. The Kremlin said it had nothing to announce yet. Ukraine's president's office did not immediately respond.
