Here's an Idea: Change Cup of China into the Yellow Sea Cup. Alternating years in the two countries on each side of the Yellow Sea: China and South Korea. Samsung could still be the sponsor at both if it wanted to be.
Seriously, nothing gets the Chinese fired up with national pride like an attendance competition. Go figure. A huge part of the Shanghai Expo was focused on distributing free tickets and bussing groups in to "beat" the previous record at the Aishi, Japan Expo of several years ago. With much fanfare when this was achieved. I could foresee a Yellow Sea Cup held in Beijing, where the previous years had 10,000 people in Seoul, and exhortations to all fans to show up and make it 11,000 to beat those !@#$% Koreans.
LOLS! Yet so true... the amount of rivalry between Korea, Japan, and China is mind-boggling- it's quite interesting listening to my mother rant about something the Japanese/Koreans did and motherland pride and shiz. XD
