Yesterday, Wang Zaixi (王在希), deputy chairman of China's Association on Relations across the Taiwan Strait (ARATS), said that after Chen Yunlin's visit to Taiwan, the next step in relations would be to negotiate a peace agreement on the foundation of the 92 concensus with the aim of establishing a framework for peaceful cross-strait development.
If this is the case, it represents even faster movement by the Chinese side in welcoming Ma's overtures than most US and Taiwan analysts have been anticipating.
My guess is that there were a couple camps of thinking in China on this topic; the first was a group that wanted to wait and see how sincere Ma was, see how likely he'd be to stay in power for a second term, and see just how much he'd give away for free before negotiating.
If Wang's statements represent establishment view, which seems likely given his rank, it means another viewpoint won out, namely that China should work while it still can to consolidate, formalize and solidify the 92 concensus and a framework that would tightly constrain any future DPP administration and help lock Taiwan into a path ultimately directed at unification.
Mind you, I'm largely speculating here, but this is a big statement from a high-ranking Chinese official. As far as I know, this is their first statement on signing a peace agreement. Previously it was just Ma talking to himself. To make such an agreement the "next step," as well, is even more surprising and I think shows a sense of urgency on the Chinese side. They know any agreement would take some time to negotiate and they are probably worried about excessive legislative oversight (LY is trying to gain 'treaty review authority' on cross-strait agreements) and about losing a window of opportunity to lock things in.
If you were hoping to ensure Taiwan's future would be decided by the Taiwanese people alone directly through referendum, I think its time to be afraid.
