What is economics education like in North Korea?

As Greg Mankiw asks. I wondered the same thing. Although I should point out that Zhang Dejiang 张德江 had studied Korean in China in the early seventies, when the Cultural Revolution was still winding down, and it was still only August 1978 when he studied econ in North Korea. At that point Deng Xiaoping had just started consolidating power, and no one could have guessed how he would transform the Chinese economy.
