The section below is at the very bottom of the article. I don't know who the Shura Council is but hopefully they are correct with the completion date...

A spokesman of the Shura Council said that various recommendations made to the government were in place to make Oman more competitive in retail sector to keep the money home.

"The Mall of Oman, the Omagine project with shopping complexes, the Exhibition and Trade Convention Centre, six international hotels, the development of Salalah beach resorts, the Sohar and the Duqm urbanisation programmes are part of the projects which are on the way to make Oman a vibrant retail centre for both local residents and visitors from neighbouring countries.

"All these projects will be completed by 2018," the Shura Council spokesman told the Times

of Oman.
