Ang is visiting Moscow to talk to his Russian counterpart Sergey Lavrov and will also meet President Vladimir Putin, according to the Kremlin.
China is ready and will take the parties' endeavors into consideration and play a constructive role in the work of finding a solution, says Wang.
Beijing has repeatedly described itself as a neutral party regarding the Russian war of aggression and has emphasized that it will not assist either party in the actual warfare.
China is, however, close to Russia both economically and politically, and NATO countries have described Beijing as a "crucial" support for Moscow to be able to continue the war, which they have never condemned.
