Diplomats are growing concerned that China could offer to resolve the Strait of Hormuz crisis in exchange for the U.S. reducing its support for Taiwan.
This potential 'grand bargain' links two of the world's most critical geopolitical flashpoints: energy security in the Middle East and the deterrence balance in the Indo-Pacific. Since late February, the Strait of Hormuz, a vital channel for about one-fifth of global seaborne oil, has been sporadically closed due to the U.S.-Israel conflict with Iran. This disruption has caused wild swings in Brent crude prices, creating immense economic and political pressure on Washington to find a solution.
So, why is a China-brokered deal suddenly on the table? The causal chain is quite clear. First, China has uniquely positioned itself as an indispensable mediator with significant leverage over Iran. Beijing is Tehran's largest oil customer, giving it economic influence that Western nations lack. Chinese officials have publicly called for safe passage while privately signaling to the U.S. that any help would come at a price.
Second, a perfect bargaining chip now exists. In late 2025, the U.S. approved a record $11.1 billion arms package for Taiwan, but the deliveries have not yet moved forward. This creates a tangible concession that the U.S. could offer—delaying or scaling back the package—in a trade that Beijing has long sought to undermine U.S.-Taiwan relations.
Third, multilateral options have been exhausted. China and Russia recently used their UNSC veto power to block a UN Security Council resolution on Hormuz. This effectively sidelines the UN and funnels any high-stakes negotiation into a bilateral channel between Washington and Beijing, where such direct trade-offs are more likely to occur.
Ultimately, Washington faces a difficult dilemma. Accepting China's help could provide immediate relief to volatile energy markets, but it would come at the cost of long-term strategic credibility and could alter the security landscape in the Taiwan Strait. The upcoming U.S.-China summit will be a key indicator of which path is chosen.
