Key Points
- Xi Jinping responded to Trump’s letter, denying that China is providing weapons to Iran
- The U.S. president had warned of imposing 50% tariffs on nations that arm Tehran
- Despite Trump’s assertion of “permanently opening” the Strait of Hormuz, maritime traffic continues to be significantly reduced
- This diplomatic correspondence precedes the scheduled Trump-Xi meeting in Beijing set for May 14-15
- A comprehensive U.S. naval blockade has brought all maritime commerce with Iran to a standstill
President Trump disclosed during a Wednesday Fox Business interview that he and Chinese leader Xi Jinping have been corresponding about allegations of Chinese arms transfers to the Islamic Republic of Iran.
According to Trump, he initiated the correspondence after intelligence reports suggested Beijing was providing military equipment to Tehran. Xi’s response firmly denied these allegations.
“I sent him correspondence requesting that he refrain from such actions, and his reply essentially confirmed he’s not engaged in that,” Trump stated during his appearance on Fox Business’s Mornings with Maria program, which was recorded the previous day.
The president had earlier issued a warning that any nation supplying arms to Iran would face 50% tariffs on their exports to the United States. This ultimatum particularly targets China, given its significant economic relationship with Iran.
While Beijing doesn’t engage in direct military hardware shipments to Tehran, it does provide technology with both civilian and military applications, a practice that has generated alarm among U.S. officials.
Continuing Crisis in Hormuz Waterway
This diplomatic exchange occurs against the backdrop of sustained disruption in the Strait of Hormuz. Iran’s Revolutionary Guards announced a closure of the strategic passage approximately 45 days ago, eliminating access to roughly one-fifth of the world’s oil and liquefied natural gas transport.
Although a 14-day ceasefire agreement is currently active, vessel movement through the channel remains dramatically below historical levels. Daily transits represent only a small portion of the more than 130 crossings recorded before hostilities erupted.
In a Wednesday Truth Social post, Trump declared he is “permanently opening” the Strait of Hormuz and claimed China is “very happy” about this development. White House officials have not provided additional context for this announcement.
As Iran’s primary oil purchaser, China faces significant economic consequences from the strait’s closure, alongside the broader impact on international energy markets.
The United States has implemented a full maritime blockade targeting Iranian ports. Military officials confirmed Wednesday that this operation has entirely eliminated all seaborne commercial activity to and from Iran.
Diplomatic negotiations between Washington and Tehran concluded last weekend without reaching any resolution. Trump indicated these discussions might reconvene in the coming days.
Forthcoming China Summit
The correspondence between the two leaders precedes Trump’s scheduled Beijing visit for a May 14-15 summit with Xi. Trump suggested that U.S. actions regarding Iran and Venezuela would not derail the planned meeting.
“I don’t believe it will. After all, he’s someone who requires oil. We don’t,” Trump remarked.
Xi addressed the Iran situation publicly for the first time on Tuesday, telling Spanish Prime Minister Pedro Sánchez that “the international order is crumbling into disarray.”
Beijing has urged all involved parties to exercise caution and restraint. New economic data released Tuesday revealed a substantial deceleration in China’s export expansion during March.
