American envoy Masad Bolus participated in the event in Egypt alongside Sudanese army chief Abdel Fattah al-Burhan, and said that Washington remains committed to finding a political solution to the Sudanese war.
The Sudanese government said the meeting was informal and no talks were held.
It came less than two weeks after the US withheld a visa for Burhan ahead of a United Nations performance amid tensions over a US-backed ceasefire proposal.
