Yemen's Southern Transitional Council and its institutions will be dismantled effective Friday.
The move paves the way for participation in the southern Yemen dialogue that will be hosted by Riyadh.
In a statement, members of the STC said the council had not achieved its desired goals. They added that they did not take part in the decision to carry out unilateral military moves in the eastern Hadhramaut and al-Mahra governorates.
They said the actions there had "harmed the Southern Cause."
Vice President of Yemen's Presidential Leadership Council (PLC) Abdul Rahman Al-Mahrami, also known as Abou Zaraa, and PLC member Ahmed Said bin Braik were present at the STC meeting.
The statement called on various officials and figures to join the dialogue, hoping that the Riyadh conference would "come up with a vision to resolve the Southern Cause."
It also expressed its gratitude to Saudi Arabia for hosting the conference.
