The crown prince told a woman reporter from Paris' Le Monde newspaper that Saudi women have entered the mainstream.
"They now work in banks and in the public sector. With time, their attitudes and those of their husbands will develop and that could take less than five years," he said.
On where he thinks Saudi Arabia will be after 20 years, Prince Abdullah said: "Only God knows. We are working on implementing true democracy, the democracy we want and wish for. I hope that can be achieved in the next 20 years."
