Following the collapse of U.S.–Iran peace talks in Pakistan over the weekend, the United States moved to impose a naval blockade on Iranian ports and coastal areas along the Strait of Hormuz—a strategy analysts say carries significant global and geopolitical implications, particularly for China.
After negotiations in Islamabad on April 12 failed due to Iran’s refusal to abandon its nuclear ambitions, President Donald Trump announced that the U.S. Navy would begin enforcing the blockade. Since April 13 at 10 a.m. ET, U.S. Central Command has applied the measure “impartially against vessels of all nations” entering or leaving Iranian ports across the Arabian Gulf and Gulf of Oman.
U.S. officials emphasized that the blockade does not restrict freedom of navigation for ships transiting the Strait of Hormuz to non-Iranian destinations.
Pressure on Iran—and China
Soon after the conflict began on Feb. 28, Iran restricted access to the Strait of Hormuz, targeting commercial vessels while allowing passage for ships from allied nations, including China. In recent weeks, Tehran has reportedly imposed transit fees of up to $2 million per voyage.
China quickly criticized the U.S. blockade, calling it “irresponsible and dangerous” and warning it runs counter to international interests.
Analysts say the blockade could significantly impact China’s economy. Roughly 40 percent of China’s crude oil imports pass through the Strait of Hormuz, and China purchases more than 80 percent of Iran’s exported oil—often at discounted prices.
Fang Wei, a U.S.-based commentator on current affairs, said Iran’s earlier restrictions violated international maritime norms by selectively allowing passage and imposing excessive fees. He argued that the U.S. blockade effectively prevents Iran from leveraging the strait as a geopolitical tool while cutting off a major source of its revenue.
“China is Iran’s largest trading partner and depends heavily on this route,” Fang said. “If Chinese vessels are blocked, China will be forced to seek alternative suppliers at higher costs, increasing economic pressure at a time when its economy is already weak.”
“Two Birds With One Stone” Strategy
Su Tzu-yun, a defense strategy expert at Taiwan’s Institute for National Defense and Security Research, described the blockade as a strategic move that indirectly targets China while confronting Iran.
By restricting access to Iranian ports, the United States is not only limiting Iran’s economic lifeline but also disrupting supply chains tied to Chinese energy and military support, Su said.
He added that the move shifts Washington from a defensive to a more assertive posture, using economic and military pressure to strengthen its negotiating position while demonstrating force.
Chung Chih-tung, another researcher at the institute, said the U.S. approach narrows the scope of the conflict by focusing specifically on Iranian ports rather than broader maritime traffic.
“By limiting the blockade to Iran, the United States is reducing wider global fallout while addressing what it views as unfair practices, such as Iran’s tolls on international shipping,” Chung said.
Broader Economic and Strategic Impact
Iran’s earlier restrictions on the Strait of Hormuz had already driven up global oil prices and disrupted logistics, placing pressure on economies worldwide, including the United States.
However, analysts note that Washington is in a relatively strong position due to its domestic energy production and access to alternative suppliers, including Venezuela and smaller oil-producing nations.
China, by contrast, may face rising costs and increased competition for oil supplies. Because many alternative suppliers require payment in U.S. dollars rather than Chinese yuan, Beijing could also see pressure on its foreign currency reserves.
Possible Future Developments
Experts suggest the situation could evolve further in the coming weeks. Some anticipate that the United States may intensify efforts to weaken Iran’s military capabilities while continuing to apply economic pressure.
Su noted that internal dynamics within Iran—between its clerical leadership, elected government, and military forces—could shape how the conflict unfolds.
He also suggested that the United States may seek to strengthen ties with Gulf nations and support regional stability efforts as part of a broader strategy.
Meanwhile, the mounting economic strain on China could push Beijing to encourage renewed negotiations between Washington and Tehran.
Analysts say the current dynamics place Iran and China under increasing pressure, while the United States retains leverage both militarily and economically as the situation continues to develop.
