Wang Yi, China's top diplomat, has arrived in Moscow for a high-profile visit that includes a meeting with Russian Foreign Minister Sergey Lavrov. The visit comes as tensions between Washington and Beijing continue to rise, with the U.S. Ambassador to the United Nations warning China against providing lethal aid to Russia in its war against Ukraine. Wang's visit is the final stop in an eight-day international tour and it is unclear what topics will be discussed, but it is likely to include the ongoing conflict in Ukraine and U.S.-China relations.
