Lien Chen's multi-faceted visit to the mainland

If we want to discuss the implications of Taiwan, we should at least jump back a bit and examine relatively recent developments that will aide us in the understanding of current fellings between Taiwan and mainland China. http://english.cctv.com/english/20050504/100060.shtml
The KMT's chairman Lien Chen, in his last visit to the mainlnand (the first in 60 years), expressed a mutual assurance that both countries are working together toward a mutual win-win relationship; however, there are undertones within the articles that echo of pride on the part of the KMT leader. For one, claimed the KMT to be the ringleaderbehind such pushes in legislation regarding the "1992 consensus" stating that the two sides will operate under their own standards so long as "we stay within the one china framework."
Frankly, as is often debated in and amongst a paranoid american public, China's overwhelming display of force militarily leave's Taiwan with no leg to stand on insofar as proposals are concerned. To an extent it's easy to agree with this, at least in the gool 'ol days, Taiwan would have little chance of fending off a kick-in-the-door invasion from the mainland; however, seeing that, ideally, we've all grown up internationally I would like to first offer the argument that economic repercussions would be more of an initiative for China and Taiwan to stick together. China's lucrative corner of the market in manufacturing allows Taiwan's major companies access to investment opportunities that would otherwise be soured by a push for independence. Furthermore, it is within China's interest to keep Taiwan within its sphere of influence (not only as an interest in pride and securing its periphery) as it is a valid assumption that those countries involved with trade or relations of any kind tend to take up policies that mimic those of their trading partners. (I'm drawing a blank on the actual term for this)
My question is this, despite the apparently friendly welcome of the KMT chairman to the mainland would a serious move for independence draw out enough controversy to sever trade relations with the mainland? I'm also curious of whether or not the KMT actually plays a large role in this as it is no longer a majority power in the unicameral Yuan. www.cia.gov/cia/publications/factbook/geos/tw.html
