Summary

China's de facto reduction in Iranian crude imports triggered formal diplomatic protests from Tehran as satellite-verified port refusals translated into measurable economic pressure on Iran's war-strained treasury. Iranian officials summoned China's ambassador to demand clarification on the sudden shift in procurement patterns, while Beijing maintained public silence on the informal arrangement with Washington. The diplomatic friction exposed the limits of Iran's strategic partnership with China when confronted with American economic leverage.
