U.S. condemns Xi-Putin meeting

U.S. Secretary of State Antony Blinken condemned the meeting between Xi and Putin Monday, calling it a “diplomatic cover” for Russia’s crimes against Ukraine, CNN reported.

“That President Xi is traveling to Russia days after the International Criminal Court issued an arrest warrant for President Putin suggests that China feels no responsibility to hold the Kremlin accountable for the atrocities committed in Ukraine, and instead of even condemning them, it would rather provide diplomatic cover for Russia to continue to commit those very crimes,” Blinken stated in a news conference.

Xi Jinping arrives in Moscow

The two countries will “jointly adopt a new vision, a new blueprint and new measures for the growth of China-Russia comprehensive strategic partnership of coordination in the years to come,” Xi continued.
