Iran's economy faces more instability.

The Trump administration is pushing other countries to end all financial dealings with the Islamic Republic.

The United Arab Emirates stopped trade with Iran last week.

This started the latest U.S. effort to isolate Tehran.

Iran's foreign trade was already limited to a small group of partners.

This leaves it with fewer choices.

The success of the U.S. plan depends mostly on China.

China is Iran's top oil buyer and trading partner.

Russia also has its own economic crisis because of wide sanctions.

So Russia can offer little financial help.

Regional partners like Turkey, Pakistan, and Iraq have ties to both Iran and the U.S.

They may avoid secondary sanctions.

Treasury Secretary Scott Bessent called the plan "Operation Economic Outcast."

He said those who stand with the U.S. will benefit.

Those tied to Iran will share its isolation.

In 2024, Iran traded $125 billion worth of goods globally.

But most of it involved a few partners.

The UAE, China, and Turkey supplied nearly three-quarters of Iran's imports.

The UAE was especially important as a re-export hub and a gateway for international payments.

Experts say Iran can replace the UAE, but not quickly.

China has economic interests beyond Iran and has avoided direct conflict.

It buys most of Iran's crude through unclear networks that bypass sanctions.

Analysts doubt China will fully follow U.S. pressure.

But China has reduced Iranian oil imports in the past.

Other partners face their own limits: Turkey settled a U.S. dispute over sanctions evasion.

Iraq depends on U.S. control of its currency reserves.

Pakistan balances ties with both Tehran and Washington.

The U.S. dollar's power means no partner would anger Washington lightly, one expert said.
