Key Takeaways

The US military has fully implemented a blockade on Iranian ports, halting nearly all economic trade entering and leaving Iran by sea. This move affects approximately 90% of Iran's economy. While six merchant ships complied with the US orders to turn around, at least two Chinese vessels passed through unobstructed.

  • The blockade involves over 10,000 US military personnel.
  • China and Saudi Arabia have condemned the blockade as dangerous and irresponsible.
  • Iran considers the blockade a violation of the ceasefire, potentially complicating future negotiations.

The US military has fully implemented a blockade on Iranian ports, halting all economic trade entering and leaving Iran by sea. According to US Central Command (CENTCOM), the blockade is being enforced against vessels of all nations in Iranian coastal areas or ports.

In less than 36 hours since the blockade was implemented, US forces have completely halted economic trade going into and out of Iran by sea. CENTCOM Commander Admiral Brad Cooper stated that an estimated 90% of Iran’s economy is fuelled by international trade by sea.

The blockade involves more than 10,000 sailors, Marines, and US Air Force personnel. In the first 24 hours, six merchant ships complied with US orders to turn around and re-enter an Iranian port. However, at least two vessels from China passed through the Strait of Hormuz without being intercepted.

China condemned Donald Trump's blockade as 'dangerous and irresponsible', risking dragging Beijing into the war. Saudi Arabia also pressed Mr Trump to drop the siege and return to talks. Iran considers the blockade a violation of the ceasefire, which could complicate the situation further.
