"The AU cannot continue these dishonest, opaque discussions which sideline participants or treat them in an unjust way," the bloc's ambassador to Sudan, Mohammed Belaiche, told reporters late Tuesday.
But the AU denied it was abandoning the so-called "troika" of sponsors of the talks process, which also includes the United Nations and East African regional grouping IGAD.
That was an "erroneous interpretation" of Belaiche's comments, its delegation said in a clarification Wednesday.
The AU suspended Sudan after the military's October 27 overthrow of a joint civilian-military transitional government installed in the aftermath of the army's 2019 ouster of longtime President Omar al-Bashir.
Many foreign donors cut off aid, which accounts for 40 percent of state revenues, prompting military leader Abdel Fattah al-Burhan to agree to talks launched by the troika this month.
But the talks have been undermined by a boycott by all significant civilian players, including both Sudan's established political parties and groups born out of the mass protests that led to Bashir's ouster.
Since US envoys failed to persuade the civilians to give the talks a chance, the process has been put on hold indefinitely.
