I'm sure this is one aspect of it. They surely don't want "foreign decadence" to influence their youth --which is part of losing control over narrative.

It's kind of typical socialist thinking that you can have forever revolutionary songs and chants, forever reconstruction and forever community activism (for the party of course). Obviously, that can work in tightly controlled environments such as North Korea, and it looks like they are taking some of that social control back so they can better dictate what they population should do (for its own good as they see it, obviously).
