While I can understand the reasoning behind not sending aid, especially fungible items like food and fuel, to a regime that bombards you, sinks your ships, and prefers nukes to feeding its own people, but underwear for kids? That would seem pretty safe from diversion to the military or corrupt officials (though I’m sure a few of the latter would be able to intercept enough to sell on the black market).
Instead, the South Korean government decided to reject a request by South Korean humanitarian organizations to send thermal underwear to children in North Korea. The Ministry of Unification reportedly turned down the request due to poor relations and the collapse of recent talks.
I’m not sure how keeping kids cold will benefit the South, but I’m sure it makes sense to some bureaucrat somewhere.
