In October 2006, for the first time, a Navarrese youth team played "Llargues" against a Valencian one during the "Pilota Day" celebrated in Valencia (in the adult match, the Valencian community team played the Frisian team from the Netherlands). At the moment the only exchanges between both sports are friendly matches of Frontó, which is the main modality for Basques but a mostly irrelevant one for Valencians. In summer, or for special events, exhibition matches are organized, as the "Open Ciutat de València", with particular rules (such as the length of the court), and balls of intermediate size and diameter (70 gr.) between the kinds that both regions are accustomed to.
