Saudi Arabia said it will stop working with foreign firms that don’t base their Middle East headquarters in the kingdom, in its latest effort to shift the Gulf region’s business hub away from Dubai. Al Jazeera reports that as part of attempts to open and diversify its economy Saudi Arabia has though offered firms a package of incentives including tax breaks under a plan dubbed “Project HQ” and that the latest move is intended to encourage foreign firms to hire more Saudi nationals and limit “economic leakage”.
