I wonder if this will actually go anywhere. Russia has illegally annexed Japanese territory following WWII in the absense of a peace treaty between the two. One large part, Japan no longer officially claims, but there are several smaller islands that are at the crux of an ongoing dispute between the two countries.
It will be interesting to see if any progress is made. Japan stands to be a huge customer for Russian natural gas, something definately in Russia's interests as they don't want to be completely dependant on China as a customer for its Far East gas reserves.
