US President Donald Trump on Monday said he had imposed a 25% tariff on goods from countries with commercial ties to Iran, a move that could put pressure on Tehran as anti-government protests enter a third week.
Trump said on social media that the tariff was "effective immediately", without offering details of what constituted "doing business" with Iran.
China is Iran's largest trading partners, followed by Iraq, the United Arab Emirates, Turkey and India.

The new tariff comes after Trump threatened to intervene militarily if Tehran killed protesters. White House spokeswoman Karoline Leavitt said on Monday that military options including air strikes were still "on the table".
"Any Country doing business with the Islamic Republic of Iran will pay a Tariff of 25% on any and all business being done with the United States of America," Trump wrote on Truth Social on Monday.
"This Order is final and conclusive," he added.
The White House did not share additional information about the tariffs, including which countries' imports will be hit hardest.

Anger over the plummeting value of the Iranian currency sparked protests in late December, which have grown into a crisis of legitimacy for Iran's Supreme Leader, Ayatollah Ali Khamenei.
The US-based Human Rights Activist News Agency (HRANA) says it has verified the deaths of nearly 500 protesters and 48 security personnel in Iran, while sources tell the BBC the death toll could be much higher. Thousands more have reportedly been arrested.
Trump has threatened to intervene, and said on Sunday that Iranian officials had called him "to negotiate" - but added "we may have to act before a meeting".
