It comes down to your assessment of the extent to which the two legal systems are comparable. The FIPA has the greatest value where the legal system is less developed or may be subject to political influence. I'm not going to be making characterizations about the systems in China—people can draw their own conclusions about that—but I suspect that part of the reason the Canadian business community is telling us they really want this is because they believe that having access to international arbitration is valuable.
