The Russian military denied Wednesday that it was planning to test its new Zircon hypersonic missiles during naval drills off the coast of South Africa this week that will coincide with the one-year anniversary of the invasion of Ukraine. China’s navy also is participating in the Indian Ocean exercises, which come at a time when Russia’s relationship with the West is at its lowest point since the Cold War, and ties between China and the United States are under serious strain. As Russian and Chinese warships prepared in South Africa for their joint drills, Russian President Vladimir Putin hosted China’s most senior foreign policy official at the Kremlin.
