Taliban officials attended a rare, United Nations-led conference of global envoys to Afghanistan on Sunday, the first such meeting Taliban representatives have agreed to engage in, after organizers said Afghan women would be excluded from the talks.

The two-day conference in Doha, Qatar, is the third of its kind. It is part of a United Nations-led effort, known as the “Doha process,” started in May 2023. It is meant to develop a unified approach for international engagement with Afghanistan. Envoys from around 25 countries and regional organizations, including the European Union, the United States, Russia and China, are attending.

Taliban officials were not invited to the first meeting and refused to attend the second meeting, held in February, after objecting to the inclusion of Afghan civil society groups that attended.

The conference has drawn a fierce backlash in recent days after U.N. officials announced that Afghan women would not participate in discussions with Taliban officials. Human rights groups and Afghan women’s groups have slammed the decision to exclude them as too severe a concession by the U.N. to persuade the Taliban to engage in the talks.

The decision to exclude women sets “a deeply damaging precedent” and risks “legitimatizing their gender-based institutional system of oppression,” Agnès Callamard, the secretary general of Amnesty International, said in a statement referring to the Taliban’s policies toward women. “The international community must adopt a clear and united stance: The rights of women and girls in Afghanistan are nonnegotiable.”

Since seizing power from the U.S.-backed government in 2021, Taliban authorities have systematically rolled back women’s rights, effectively erasing women from public life. Women and girls are barred from getting education beyond primary school and banned from most employment outside of education and health care, and they cannot travel significant distances without a male guardian.
