Korean Political History II: Chapter 7, Exercise 3 — Possible Solution
======================================================================

WHAT IT SIGNALS
The source says analysts called the change a "de-ethnification" of policy: it
treats the two Koreas as separate states, not parts of a single nation, which
fits Kim Jong Un's 30 December 2023 statement that they are "separate ethnic
nations".

WHAT THE SOURCE DOES NOT TELL YOU
- When exactly the terminology changed.
- Which documents or media adopted it.
- The party-side decision behind it (Chapter 3 records only that the party
  abandoned the reunification goal in 2023).
