East African dominance over track events has largely ended. The 1500m world record is held by a West African, while the mile and 3000m world records are now held by white Europeans. The 5000m at the recent World Championships had no East African medalists, and the 10000m had just one. Same goes for the most recent Olympic 5000m.

Compare this with the Olympic and World Championship podiums for the 2000s and 2010s; I don't believe a non-East-African-born athlete won a single 5000/10000m medal for 20 years straight.
