According to an article at DigiTimes, the DVD+RW Alliance has decided to set up compatibility and testing group in Taiwan.
The DVD+RW Alliance, in light of Taiwan's importance in the production of optical discs and drives, will set up a Taiwan branch of its DVD+RW Compatibility and Convergence Group (DCCG), the Taiwan Compatibility and Convergence Group (TCCG), tentatively by September of this year, according to the alliance at a seminar in Taipei on July 19.

Currently, Taiwan-based makers of DVD+R/RW burners and discs have to send their products to DCCG in Japan for compatibility testing and verification and the establishment of TCCG will reduce time and costs for the makers, according to industry sources.
The article also mentions that DCCG has offered certification for 8x DVD+RW DL discs to several makers and plans to finish the specs for 16x DVD+RW DL media at the end of this year. If you'd like to read more, head on over to DigiTimes.
