U.S. President Donald Trump said on April 12 that China could face a 50 percent tariff on its exports to the United States if it is found to be supplying weapons to Iran.
In an interview with Fox News, Trump referenced reports claiming that China may be providing military equipment to Tehran, including shoulder-fired anti-aircraft missiles, though he expressed skepticism about the claims.
“I hear news reports about China giving shoulder missiles—what’s called a shoulder missile, anti-aircraft missile. I doubt they would do that,” he said. “But if we catch them doing that, they get a 50 percent tariff, which is staggering.”
Trump had previously warned that any country supplying weapons to Iran during the ongoing conflict would face immediate 50 percent tariffs on exports to the United States, as a temporary two-week ceasefire took effect.
Failed Talks and Escalating Measures
Peace talks between U.S. and Iranian officials ended on April 12 without an agreement. Vice President JD Vance said Tehran refused to abandon its pursuit of nuclear weapons.
Following the breakdown in negotiations, Trump announced that the U.S. Navy would enforce a blockade targeting ships traveling to and from Iranian ports through the Strait of Hormuz. U.S. Central Command (CENTCOM) confirmed that the operation is intended to restrict access to Iranian ports while allowing free passage for vessels heading to non-Iranian destinations.
Shipping activity through the strategically vital waterway—which handles a significant share of global oil and gas transport—has been severely disrupted since late February. At that time, U.S. and Israeli forces launched strikes on Iran, prompting retaliatory drone and missile attacks by Iran on U.S. and Israeli targets across Gulf nations. Iran has also deployed sea mines in the strait and sought to impose fees for safe passage.
CENTCOM stated that the blockade of Iranian ports would begin on April 13 at 10 a.m. EDT (5:30 p.m. Tehran time). The command emphasized that U.S. forces would not interfere with freedom of navigation for vessels transiting the strait, provided they are not entering Iranian ports.
In addition, U.S. forces have initiated mine-clearing operations in the area to help ensure safe passage for international shipping. Trump described the effort as beneficial to countries worldwide, including China, Japan, South Korea, France, and Germany.
U.S.–China Relations and Upcoming Talks
Trump is expected to meet Chinese leader Xi Jinping in Beijing on May 14, after postponing an earlier April meeting due to the conflict with Iran.
The upcoming talks will mark their first in-person meeting since the APEC summit in Busan, South Korea, in October 2025. The two leaders also spoke by phone in February, ahead of a U.S. Supreme Court decision that struck down Trump’s use of emergency powers to impose tariffs.
Following that ruling on Feb. 20, the administration launched new trade investigations into China and other countries under measures such as Section 301 of the Trade Act of 1974, which examines potentially unfair trade practices.
U.S. Trade Representative Jamieson Greer said on March 12 that the probes are aimed at determining whether foreign governments have done enough to prevent the import of goods produced with forced labor, and how such practices affect American workers and businesses.
