Welcome to the forum, konikat. I managed to find this:

Sejung is a $500 million Korean-based textile, construction and information technology business that got it's start in 1974. Yet the story of it's musical instrument company only began to unfold in March 2001. Company chairman, Soon Ho Park was presented with a plan to construct a new piano and guitar factory in China, staffed by experienced Korean managers, to supply product to local and worldwide markets.

Our S101 and Canvas line of guitars offer superb playing instruments for beginners to seasoned veterans. It is our goal to provide quality musical instruments at the most economical prices.
I've seen comments that Qingdao Sejung Musical Instruments is one of those factories that mostly makes instruments under contract for other companies, but no real proof of that. Who knows, maybe more of us than realize it have played something from the same company...
Regarding the old forum and its archives, you can dig up a little bit through Google - hopefully this works for others:
