Government Urging Purchases of Local Products

Is this a measure that can be challenged in WTO dispute settlement:

[French] Industry Minister Arnaud Montebourg donned France's emblematic striped Breton sweater for a magazine cover published last week to urge local consumers to favour French products ...

How about this:

Montebourg ... wants supermarkets in France to set up shelves with purely French products as they do for organic goods ...

I wish I had more details on exactly what the Minister did and said; that would make the analysis easier.
