US Expands Iran Sanctions, Pressures G20 as China Pushes Back

In late August 2026, the United States announced a major expansion of economic sanctions against Iran. The new measures targeted 60 entities, including several with ties to China. The move was part of a broader strategy by the Trump administration to increase pressure on Iran, especially as the conflict in the region continued to disrupt global oil markets.

China reacted quickly and strongly. Officials in Beijing condemned the US sanctions and warned that they would defend China's economic interests. They also pledged to maintain their trade relationship with Iran, signaling that Washington's efforts to isolate Tehran could face serious resistance.

On August 31, 2026, finance ministers and central bank leaders from the G20 gathered in Asheville, North Carolina. The US, as host, put Iran sanctions and global trade imbalances high on the agenda. According to Euronews, the meetings were set against a backdrop of rising energy prices and mounting debt concerns.

Reports from Greek outlet in.gr and NewsIt.gr described how the US was not only imposing new tariffs on some allies but also pressing them to join the economic campaign against Iran. Treasury Secretary Scott Bessent arrived at the G20 aiming to rally support for these efforts, as covered by the New York Post and Fast Company.

Tensions with China were front and center. According to The Hill, Bessent urged G20 members to reconsider their ties with China, citing its trade surplus and export-driven strategy. Al Jazeera reported that the US also encouraged G20 countries to adopt similar tariffs and restrictions on Chinese goods.

The meetings were marked by further controversy. The US Treasury barred several major news organizations from covering the G20, as reported by Times of India and Deutsche Welle - Persian. European officials were also upset by the presence of Russia's finance minister, but the US focus remained on sanctions and trade.

By September 1, most G20 members backed a final statement supporting action against "cheap exports" and economic distortions, but China stood alone in dissent, according to The Independent and Japan Times. Treasury Secretary Bessent publicly called out China for refusing to agree that "cheap exports" were unsustainable.

The US has succeeded in getting most G20 members to agree on the need for tougher measures against Iran and to address global trade imbalances. However, China remains defiant, rejecting both the sanctions push and calls to curb its export strategies.

According to CNBC and Fast Company, the Trump administration is now threatening secondary sanctions on Iran's business partners, raising the stakes for countries that continue economic ties with Tehran. The split between the US and China on these issues remains wide, and the G20 meetings ended without full consensus.

The next steps will likely involve the US pressuring allies to enforce secondary sanctions against Iran, and possibly expanding tariffs on Chinese goods. China's response, and whether it deepens its ties with Iran, will be critical for global markets.

Upcoming G20 and world leader summits may reveal whether this divide grows, or if any compromises are possible on sanctions and trade.
