Iran emerged from years of economic isolation on Saturday when world powers lifted crippling sanctions against the Islamic Republic in return for Tehran complying with a deal to curb its nuclear ambitions.

The U.N. nuclear watchdog ruled on Saturday that Iran had abided by an agreement last year with six world powers to curtail its nuclear programme, triggering the end of sanctions.

“Iran has carried out all measures required under the (July deal) to enable Implementation Day (of the deal) to occur,” the Vienna-based International Atomic Energy Agency said in a statement.

Within minutes, the United States formally lifted banking, steel, shipping and other sanctions on Iran, a major oil producer which has been virtually shut out of international markets for the past five years.

The European Union also began the process of lifting sanctions and Iran’s transport minister said Tehran plans to buy 114 civil aircraft from European aircraft maker Airbus.

The end of sanctions means more money and prestige for Shi’ite Muslim Iran as it becomes deeply embroiled in the sectarian conflicts of the Middle East, notably in the Syrian civil war where its allies are facing Sunni Muslim rebels.

America’s thaw with Iran is viewed with deep suspicion by U.S. Republicans as well as American allies in the Middle East, including Israel and Saudi Arabia. U.S.-Iranian suspicion still remains deeply entrenched.

Washington maintains separate, less comprehensive sanctions on Iran over its missile programme. For its part, Iran detained 10 U.S. Navy sailors on two boats in the Gulf a week ago, although they were released the next day.
