North Korea: 2012-2016

[Dayuhan]

It would be possible to create the feeling that North Korea's behaviour and existence is a shame to them, since it's their backyard and they don't keep it calm.

Possible for who exactly to create this feeling? How do you propose to create this feeling, and why do you think the Chinese give a hot round one about any feeling that anyone tries to create?

Turn that perception into one of North Korea actually damaging the standing of China

Among whom do you propose to create this perception, and how?

Turn North Korea into China's problem, period. And I mean China, not just the Chinese government. Everything from caricatures and jokes up to political speeches in front of cameras and ruining days they intended to shine on.
Make them *want* to clean up the North Korean mess.

Neither you nor I nor anyone else can make the Chinese want to do anything. They really don't care.

PS: That's aside from the reality that even if the Chinese wanted to try and "fix" North Korea it's not likely that they could, and the effort would almost certainly create more problems for them than it would solve, as efforts to "fix" other countries usually do. Why would they want to step into that kind of mess just because some unspecified person, nation, or group of people or nations is making a transparently manipulative attempt to embarrass them? The Chinese are in no way omniscient, but they aren't that stupid. Nobody's that stupid, except perhaps the Americans.
