Meanwhile, Tehran is lobbying hard against the resolution and its Western backers.
“With a long history of colonialism and human rights violations of other nations, the United States and Europe are unable to be seen as human rights defenders,” Iran’s Foreign Ministry tweeted on Wednesday.
Foreign Minister Hossein Amir-Abdollahian recently tweeted at Baerbock that his country’s response to Germany’s “provocative, interventionist and undiplomatic positions” would be “proportionate and decisive”.
Germany and Iceland gave broad support to the request for Thursday’s session, including more than a third of the council’s 47 members.
Western diplomats expressed cautious optimism that the resolution would pass, but German Foreign Ministry spokesman Christopher Burger admitted to reporters that “success in getting a majority is far from certain.”
The Human Rights Council has seen growing pressure from countries including China, Russia and Iran against efforts, often led by the West, to hold individual states accountable for alleged abuses.
Western powers suffered a crushing defeat last month when efforts to put China’s alleged abuses in the Xinjiang region on the council’s agenda were blocked.
But Iran may have a harder time blocking a resolution on Thursday.
The council has already raised concerns about Iran’s human rights by appointing a so-called special rapporteur to monitor the country in 2011 and voting to renew that mandate every year since.
“It has to pass,” said Omid Memarian, an analyst at Democracy Now for the Arab World.
He told AFP it would give protesters a “huge morale boost” and send a warning to lawbreakers in Iran that “the rest of the world will not be safe for them”.
