"Everything is on track. 2018 is our target. There is nothing that I know about that can take us off track," Public Investment Fund Managing Director Yasir al-Rumayyan told a major investment conference in Riyadh.
Asked if the possible involvement of investors such as the Chinese would delay the IPO, Rumayyan said it would not.
Rumayyan sits on the board of Saudi Aramco.
