The European Union confirmed on Monday it had reimposed sweeping sanctions on Iran over its nuclear program, after the United Nations reinstated its overarching measures.

“Today, the EU reinstated sanctions against Iran in response to its continued non-compliance with the nuclear agreement. The door for diplomatic negotiations remains open,” said the EU presidency in a statement.

The EU said the sanctions included freezing the assets of the Iranian Central Bank and other Iranian banks, as well as travel bans on certain Iranian officials.

It also banned Iran’s purchase and transportation of crude oil and the sale or supply of gold and certain naval equipment.

The UN took the same step over the weekend after Western powers triggered the so-called “snapback” mechanism under the 2015 nuclear accord.

The sanctions reintroduced by the 27-nation bloc included UN measures barring dealing with Tehran’s nuclear and ballistic missile activities.

Like the EU, they also range broader to encompass financial measures.

Tehran has condemned as “unjustifiable” the reinstatement of the UN sanctions.

Israel hailed them as a “major development in response to Iran’s ongoing violations, especially on its military nuclear program.”

Despite the reimposition, Western leaders stressed the channels for dialogue remained open.

Kaja Kallas, the European Union’s top diplomat, said on Sunday the reimposition of sanctions “must not be the end of diplomacy.”

Iran has long contended that it is not seeking nuclear weapons, but it has been enriching uranium to levels that have no peaceful application, barring UN nuclear inspectors, and regularly threatening to flatten Israeli cities.

The sanctions are a “snapback” of measures frozen in 2015 when Iran agreed to major restrictions on its nuclear program under a deal negotiated by former US president Barack Obama.

The United States already imposed massive sanctions, including trying to force all countries to shun Iranian oil, when US President Donald Trump withdrew from the deal in his first term.

Iran and the United States had held several rounds of Omani-brokered talks earlier this year before they collapsed in June when first Israel and then the United States attacked Iranian nuclear facilities.
