Iran’s Secretary of the Supreme National Security Council (SNSC), Mohsen Rezaei, has warned neighbouring countries against joining the United States’ economic campaign against Tehran, saying such participation would lead Iran to consider them enemies.

In an interview with IRIB, Rezaei said, Iran is not seeking escalation but warned that Tehran would respond if neighbouring countries supported Washington’s economic pressure measures. He further warned that Iran could block oil exports from the Persian Gulf and the Strait of Hormuz if regional countries joined the US campaign.

His remarks come after US President Donald Trump announced what he described as an “Economic D-Day” campaign against Iran, calling it the “most crushing economic operation ever taken against any country” and urging US allies to join Washington in isolating Tehran.

Trump said the new measures would target Iran’s economic lifelines, including oil smuggling networks, financial transfers, exchange houses, ship registries and front companies.
