Personally i'm supportive of a peaceful reunification of Korea, and i'm sure China is too.
However for this to happen, NKorea must be better developped and more economically stable, which would require the help of both China and SKorea, if not then it would be the same as German reunification, much worse if a war happened, in such a scenario SKorea's economy would suffer horribly, having to pay for the damages and reconstruction of the north, along with dealing with mass refugees.
If the first scenario were to happen though, SKorea would no longer need the US as a major ally, largely because their alliance is based on the fact that the South needs to be protected from the North, without the North, the South will seek greater independence from the US, and i doubt the US will be able to maintain its miltiary presence on the grounds of the China threat, i think the SKorean government will be mroe likely to see China as an important ally and trade partner in the future.
