Other envoys from Germany, Austria and Italy were also cancelling their involvement in the Dec. 14 event, the French foreign ministry said on Twitter. At the foot of its tweet, the ministry ran the hashtag #nobusinessasusual.
In a separate statement, organisers of the Europe-Iran business forum later said they were postponing the event.
Earlier, Iran’s Foreign Ministry summoned the envoys from France and from Germany, current holder of the European Union’s rotating presidency, to protest over French and EU criticism of the execution on Saturday, Iranian media reported.
France on Saturday called Zam’s execution “barbaric and unacceptable”, and said it ran counter to Iran’s international obligations. Zam had been based in Paris before he was captured in Iraq and taken to Iran.
Zam was convicted of fomenting violence during anti-government protests in 2017. His Amadnews feed had more than 1 million followers.
France and its European allies have strived to keep alive a 2015 nuclear deal between Iran and major powers, in part to save the Iranian economy from collapse, while confronting U.S. efforts to kill the accord.
The new friction over human rights comes as U.S. President-elect Joe Biden, who is set to take office on Jan. 20, has said he will return the United States to the Obama-era deal if Iran resumes compliance with the agreement.
The EU also strongly condemned Zam’s execution, as did Amnesty International and press advocacy group Reporters Without Borders (RSF).
Iranian officials have accused the United States, as well asTehran’s regional rival Saudi Arabia and government opponentsliving in exile, of stoking the unrest that began in late 2017as regional protests over economic hardship spread nationwide.
Officials said 21 people were killed during the unrest andthousands were arrested. The unrest was among the worst Iran hasseen in decades, and was followed by even deadlier protests lastyear against fuel price rises.
