International Cooperation: China-EU Relations

So there has been a lot of interaction between EU and China, as of recently. I'll start with the following article from the Chinese Embassador to the EU, where he praises the Lisbon treaty and it's ability to increase European integration, thus endowing the EU with a new authority and consequent ability in international relations, fundamental to the EU-China foreign strategic relationship (whatever it may be...).

Then we follow with the renewed calls for Beijing to allow the renmimbi to float, which is really to say that the EU and the USA want it to appreciate.

The Chinese on the other hand want to leave it be for fear it'll create chaos, which I'm assuming they fear would be large enough to topple the single party regime.

At the same time the Chinese seem to have requests of their own, involving European countries giving up some of their IMF seats.

What does all this chatter mean?
