TLDR
- Chinese President Xi Jinping assured Trump in writing that Beijing is not providing weapons to Iran
- Trump had issued a warning of 50% tariffs against nations supplying arms to Tehran
- Despite Trump’s claims of “permanently opening” the Strait of Hormuz, shipping traffic remains significantly reduced
- The diplomatic correspondence occurred in the lead-up to a scheduled Trump-Xi meeting in Beijing on May 14-15
- American forces have implemented a complete naval blockade of Iranian ports, stopping all maritime commerce
In a Fox Business interview broadcast on Wednesday, President Trump disclosed that he and Chinese President Xi Jinping recently exchanged correspondence concerning allegations of Chinese weapons shipments to Iran.
According to Trump, he initiated the exchange after intelligence suggested China might be transferring weapons to the Islamic Republic. Xi’s response categorically denied such activities.
“I wrote him a letter asking him not to do that, and he wrote me a letter saying that, essentially, he’s not doing that,” Trump explained during his appearance on Fox Business’s Mornings with Maria program, which was recorded the previous day.
The President had earlier issued warnings of imposing 50% tariffs on merchandise from any nation providing military equipment to Iran. This ultimatum carries particular weight for China, given Beijing’s status as one of Tehran’s most significant economic allies.
While China doesn’t engage in direct arms shipments to Iran, it does provide dual-use technology—equipment with both civilian and military applications—which has become a source of anxiety in Washington.
Strait of Hormuz Disruption
This diplomatic exchange occurs against the backdrop of prolonged disruptions in the Strait of Hormuz. Approximately 45 days ago, Iran’s Revolutionary Guards announced the closure of this critical waterway, effectively blocking roughly one-fifth of worldwide oil and liquefied natural gas transportation.
While a two-week ceasefire arrangement is currently active, vessel traffic through the strategic passage remains substantially diminished. Daily transits represent only a small fraction of the 130-plus crossings recorded before hostilities erupted.
On Wednesday, Trump announced via Truth Social that he is “permanently opening” the Strait of Hormuz and that China is “very happy” about this development. White House officials have not provided additional context for this declaration.
As the primary purchaser of Iranian crude oil, China faces significant economic consequences from the strait’s closure, alongside broader disruptions to international energy markets.
US Blockade of Iran
The United States has implemented a comprehensive blockade of Iranian maritime facilities. On Wednesday, US military officials confirmed that the blockade has successfully stopped all seaborne trade entering or leaving Iran.
Diplomatic negotiations between Washington and Tehran concluded last weekend without reaching any settlement. Trump indicated that discussions might recommence within days.
Upcoming Beijing Summit
This epistolary diplomacy precedes Trump’s scheduled trip to Beijing for a May 14-15 summit with Xi. The President indicated that US actions regarding Iran and Venezuela would not derail the planned meeting.
“I don’t think it does. I mean, he’s somebody that needs oil. We don’t,” Trump remarked.
On Tuesday, Xi broke his silence on the Iran situation, commenting to Spanish Prime Minister Pedro Sánchez that “the international order is crumbling into disarray.”
Beijing has urged all involved parties to exercise restraint. Economic data published Tuesday revealed a marked deceleration in China’s export expansion during March.
