Antony Blinken, the U.S. Secretary of State, has expressed concerns over China’s support for Russia’s war efforts in Ukraine. This comes just over a week before the NATO summit in Washington. Blinken addressed this issue at the Brookings Institution, a Washington-based think tank, stating that China’s actions are seen as a significant security threat to Europe, a sentiment shared by China’s neighbors in Asia, South China Morning Post reported on Tuesday. Blinken said China was helping fuel "the biggest security threat … since the end of the Cold War" for Europe.
