It's possible there's a semi-legit reason this is a good idea, like maybe their own domestic goat industry was crushed by past communist boondoggles, or just never fully developed, and they have waste of some kind that could be going to goat farming. Or yeah, it could be a "let them eat cake" moment.
Direct Kim cronies eat great food shipped directly from China. Goat meat is probably for the local jackboots, with the commanders getting the good parts.
