European companies will be protected from the impact of new sanctions imposed by the United States on Iran, Britain has said.
They are aimed at modifying Iran's behaviour, not bring about a "regime change" targeting President Hassan Rouhani, the officials added.
Trump declared the landmark 2015 agreement had been "horrible", leaving the Iranian government flush with cash to fuel conflict in the Middle East.
It called on the worldwide community "not to allow such significant achievements in multilateral diplomacy to be sacrificed in the name of American aspirations to settle political scores with Iran".
Trump renewed his attack on the worldwide nuclear pact, calling it "a frightful, one-sided deal" that "failed to achieve the fundamental objective of blocking all paths to an Iranian nuclear bomb", while giving it "a lifeline of cash" when earlier sanctions were lifted.
PSA (PUGOY), which makes Peugeot and Citroen cars, said in June that it has begun to suspend its joint ventures in the country in order to comply with USA law.
"Since the deal was reached, Iran's aggression has only increased", Trump said.

Furthermore, the European Union blocking statute does not recognise any court ruling enforcing United States sanctions.
Iranian Foreign Minister Mohammad Javad Zarif told reporters the global reaction to Trump's move showed that the USA was diplomatically "isolated", but acknowledged the sanctions "may cause some disruption". The U.S. move has dismayed America's European allies trying to preserve the nuclear deal.
The ministers said the Iran deal is "crucial for the security of Europe, the region and the entire world", and the European Union issued a "blocking statute" Monday to protect European businesses from the impact of the sanctions.
