Summary

China and Russia exercised their veto power at the United Nations Security Council to block a US-led resolution aimed at reinstating or strengthening sanctions against Iran. This diplomatic maneuver undermines the US strategy of economic pressure and signals continued Sino-Russian support for Tehran's sovereignty and nuclear program, complicating Western efforts to isolate Iran diplomatically.
