> Any civilized world will oppose hacker attacks or terror threats. But a movie like ‘The Interview,’ which makes fun of the leader of an enemy of the U.S., is nothing to be proud of for Hollywood and U.S. society,” an editorial in the newspaper said. “No matter how the U.S. society looks at North Korea and Kim Jong-un, Kim is still the leader of the country. The vicious mocking of Kim is only a result of senseless cultural arrogance.[1]
China's position on this particular incident is just a reflexive defense of the concept of "no interference in other countries' affairs, regardless of how bad they look" something which China strongly advocates for its own reasons, not for the benefit of NK.
China's general attitude over the last decade or two has been a gradually increasing private irritation with NK's behavior and while China still tends to defend NK in public, these defenses seem more and more perfunctory as time goes on. There's a sense that while they value NK as a communist buffer state, the Chinese government has little love for the NK regime in particular, and wishes they'd get their act together.
