NEC has sponsored the world championship "NEC Masters" and the world tour held by the International Tennis Federation since the start of those tournaments for over 30 years in order to promote the sports for people with disabilities, social participation of people with disabilities and social awareness.

The competitive level of wheelchair tennis is relatively high compared with other sports for those with disabilities, making it one of the most systemized sports for the disabled, while the world rankings are updated every week by the International Tennis Federation (ITF) that also governs regular tennis.
