thats what nk is charging the russians. i bet the nk are paying their soldiers 20$ a day.  plus all expenses. which could easily rack up if they are bringing fighting vehicles with them. puts its still a steal for putin, especially if he can pay with natural gas. i would imagine the north koreans want at least part of thier pay in cash, but they would have to also be willing to accept part of the pay in resources or trade goods.  its a really high iq move by both of them when you think about it. north korea has a one million standing man army, and its mostly infantry. they can throw soldiers into the ukrainian meat grinder all day long and never even notice. kim can easily mobilize more men.  north korea has the worlds fourth largest military, if ranked by active duty persoanlle. roughly 1.3 million.  kim could easily send 10% of his military and not even notice it gone.  his air force is garbage, his navy a floating joke, but his army is something else.  having them go earn some money is a very smart idea. costs him nothing.
