Trump's '60-day talks' fail, pushing US toward economic war with Iran amid China sanctions dilemma

The United States is poised to implement a new wave of severe sanctions against Iran, following the expiration of a 60-day negotiation period on July 17 without any breakthrough. The Trump administration is shifting its focus from military escalation to economic isolation, aiming to cripple Iran's oil exports.

“

We are going to be applying sanctions, very strong sanctions, on Iran.

Key targets of the impending sanctions include China's "teapot" refiners, small, independent companies that process a significant portion of Iran's crude oil exports. China is Iran's largest oil customer, importing over 80% of its seaborne crude in 2025. However, sanctioning individual teapot refiners may prove insufficient due to their limited ties to the US financial system.

Consequently, the US Treasury is considering extending pressure to China's financial networks, which handle transactions for Iranian oil. While the US has already sanctioned smaller Chinese and Hong Kong institutions involved in processing Iranian oil payments, it has also warned two major Chinese banks that they could face sanctions if Iranian funds pass through their systems. This broader approach seeks to choke off payment and remittance channels, thereby curtailing trade in Iranian crude.

“

We are going to be announcing measures that are unprecedented in terms of their scope and the pressure that they will bring to bear.

The US is also exploring ways to block Iran's alternative trade routes, potentially by sanctioning currency exchange firms in the UAE and further pressuring its "shadow oil fleet" and air cargo networks. However, experts note that Iran continuously creates new entities to circumvent sanctions, making a whack-a-mole approach ineffective in fundamentally altering its behavior.

“

Iran continues to create new entities to intermediate oil payments, and chasing individual entities is a whack-a-mole game that has not fundamentally changed Iran's behavior.

This intensified economic pressure presents a complex challenge for the Trump administration. Imposing sanctions on major Chinese banks could reignite tensions with China ahead of a planned summit between Presidents Trump and Xi Jinping. Furthermore, a significant reduction in Iranian oil supply could drive up global oil prices, a move that could be politically damaging for Trump ahead of the November midterm elections. Analysts suggest that without prioritizing Iran over China, the effectiveness of these new sanctions in changing Iran's stance remains uncertain.

Unless President Trump prioritizes Iran over China, the additional sanctions are unlikely to substantially change Iran's behavior.
