I concur with what Mr. Steiner has indicated.
Just to follow up on that, I also find it a very curious logic. I see it as nothing more than a red herring and a scare tactic. The benefits of listing a mining company in Canada, including tax laws and relatively lax disclosure requirements, far outweigh any benefits they will find in London or New York, and they're not going to go to Beijing.
I find the whole argument to be somewhat curious. Why would they leave? Is it because they risk losing publicly funded support if they violate the standards they already claim to be meeting and exceeding? There's something strange in that logic.
