etaiwannews has a story up that confirms this:
The charges covered games in Taiwan’s Chinese Professional Baseball League between 2006 and 2009, but suspicions have expanded to the Olympics because several members of the gambling syndicate traveled to China at the time and several of the indicted players were part of the Taiwanese team, reports said.
At the Olympics, Taiwan first led by 2-0 and later by 7-3, but after a game full of surprises, the national team lost 7-8 to China, a country without any reputation in baseball.
What a mess...

There really isn't much on this right now, but a number of articles are pointing to an article in the China Times (a paper out of Taiwan) that connects some of the players named in the CPBL scandal as being present in China when Taiwan beat China at the Olympics in 2008. It seems investigators are now checking to see if there might be any links between the two.
