I don't know how much they import from China (probably a lot, as you say, they have poor relations with very few other nations), but I do know some charities operate in North Korea and often come in through China. A twist is that many of these charities are operated by churches, which often leads to their running afoul of authorities in both countries (but mainly North Korea).
