Did Jeune Ecole influence other navies' strategies?

Did the idea of Jeune Ecole affect anyone else's strategy?

Yes. France's concentration on torpedo boats and commerce raiding warned other navies against an unbalanced fleet, while those capabilities remained useful within a broader flotilla-defence strategy.

The French experience influenced strategic thinking before the First World War and during the interwar period because no navy wanted to repeat its imbalance. Political enthusiasm had concentrated the French force around one attractive answer and left it weaker when opponents chose a different problem. Torpedo boats and commerce-raiding cruisers were not inherently useless; the failure came from treating them as a complete naval strategy. The lesson was institutional as much as technical because other navies studied both the weapon and the consequences of overcommitting to it. Folded into flotilla defence beside cruisers and a battle fleet, many of the same capabilities made operational sense.
