No doubt Canada needs foreign investment in order to thrive.  It's been that way for several centuries.  Originally it was British investment.  Then American.  The amount of Chinese investment currently is very small relative to American ownership so maybe this is a big fuss about nothing.  But I wonder if Mr Lu is prepared to allow Canadian investors to buy Chinese military suppliers?  Is he open to having Canadian companies control their communications companies?  Lastly, does he realize that Chinese state sponsored businesses have a leg up on private investors because they don't need to report to "shareholders"?  Why would we allow that kind of subsidy in an open economy?
