CSE spying prior to 2010 G8/G20 summit

A snippet recently published by Der Spiegel from one of the documents in the Snowden archive reveals the title of one of CSE's SIGINT reports: "2010 G8/G20: German and South Korean Officials Discuss G8/G20 Issues".

The snippet also lists the serial number of the report, 3/UU/97037-09. The Producer Designator Digraph UU in the sequence confirms that it is a CSE report. (NSA is OO, GCHQ is AA, ASD is EE, and GCSB is II; certain specific units or activities within these organizations have separate PDDGs that are used when those bodies are the originator of the report.) The 3 at the beginning indicates that the report is classified Top Secret COMINT. (Z-3 means Top Secret COMINT NOFORN, G means Top Secret COMINT-GAMMA, and other numbers and letters indicate other classifications.) The two-digit number at the end of the serial number indicates the year the report was released, in this case 2009, and the five-digit number (97037) is the number specific to that particular report.

As its title indicates, CSE's report concerned German and South Korean discussions related to the 2010 G8 and G20 summits, which were held in Canada in June 2010. It is likely that CSE (and allies) mounted an extensive effort to monitor the positions and internal deliberations of the non-Five Eyes delegates at those summits, as GCHQ and friends did during the 2009 G20 summit in the U.K. Interestingly, the serial number on the CSE report indicates that it was released in 2009, showing that CSE was collecting intelligence on this topic long before the Canadian summits actually began.
