There's something like 3 Chinese players currently playing in the top division of leagues throughout Europe.
The CSL is not the highest quality (although Guangzhou Evergrande did win the Asian CL recently), but has much more money in it than the SPFL.
Derek Riordan was on £30.000 during his short stint at Shaanxi Chanba.
Any Chinese player who does come to Scotland, would be of a level that the only boost in interest / viewing numbers would be said players direct family.
Bundesliga, La Liga, Serie A plus the EPL are the only leagues of interest within China, and even then that's reflected more in shirt-sales rather than viewing figures.
Most popular TV sport in China just now is the NBA.
