The United States is reportedly preparing sanctions against Chinese banks that support Russia's military efforts, as revealed by multiple sources including The Wall Street Journal and Bloomberg. These sanctions aim to cut off these banks from the global financial system, leveraging the power of the dollar to influence Beijing's geopolitical stance. The move is timed ahead of U.S. Secretary of State Antony Blinken's visit to China, intending to use the threat of financial isolation as diplomatic leverage. Washington's strategy reflects concerns that ongoing trade between China and Russia, particularly in dual-use trade, could bolster Moscow's ability to rebuild its war machine, potentially threatening broader European security.
