Following a new sponsorship deal between the International Equestrian Federation (FEI) and the Saudi Equestrian Fund, the Jumping Nations Cup was "renamed" and will now be known as the 'Furusiyya FEI Nations Cup Jumping' [Furusiyya is the Arabic word for 'horsemanship'].
Under the new rules, the world has been divided into six regions for the purpose of qualifying teams for a world Final. Arab nations never had qualifying teams however now.....they officially do.
