Among the interesting stories this past week, Kim Jong-nam, the (older) half brother of North Korea's leader Kin Jong Un, was assassinated in Malaysia. Several North Koreans are in custody.
But the interesting bit is the response from China, where he has been resident for some years. China is said to feel insulted as a result. Not to mention frustrated by North Korea's latest missile test. And it now appears that they are going to do something about it.
China is North Korea's biggest trading partner by far. And the biggest export North Korea has is coal. So it matters that China has suspended all coal imports from North Korea. Immediately and for the rest of 2017. That's going to hurt Kim John Un where it hurts: in the ability to buy the luxury imports that he loves.
No doubt there are other things happening in the world outside as well. Have at!
