The speech is a distillation from the internal discussions regarding:
1.  North Korea;
2. the adoption of limited free market participation;
3. the pressure that China is placing on competitors for territorial claims;
4. its substantial and growing trading clout;
5. its increasingly prominent position as a partner in major world institutions, eg the UN;
6. its apparently successful governance as reflected by China's current wealth, and world stature;
7. etc.

I guess it is an invitation of sorts to countries like North Korea to discuss leadership and political models. I suspect that NK won't bite, although there may be enough discussion at leadership levels to question a path which puts it on what is apparently an inevitable course to war. One of the things that NK has lacked, compared with the USSR and China, is a state security force with constant and direct exposure to life abroad, and the inevitable internal discussion that may  generate.
