FIFA's executive committee have chosen New Zealand to host the Under-20 World Cup and Chile for the Under-17 event.
The decision dashed Wales' hopes of hosting either, hot on the heels of losing a bid in January to host UEFA's 2013 European Under-21 Championships.
They were also up against Russia and Tunisia for the Under-17 World Cup while Tunisia, Peru were the other bidders for the Under-20 tournament.
