The One Piece manga has been released in Dutch by Glénat, which has also released the series in French. Glénat released the first 15 volumes, but has stopped publication from then on, most likely due to disappointing sales. The last Dutch One Piece volume was released March 2012.
On January 2014 the anime was broadcasted in the Dutch speaking part of Belgium for the first time. On the channel 2BE. It was a subbed version of the English dubbed anime.
The channel MCM broadcasts the new French Dub on a regular basis. An interesting note is that many of the new French dub actors come from Belgium.
