The great value of this agreement for Canadian investors is that China has accepted legally binding obligations not to discriminate against them, to provide a minimum standard of treatment, not to expropriate their investments without compensation, and to refrain from prohibited performance requirements. These are meaningful obligations, all backed up by the ability to challenge violations by taking a case before international arbitration. This provides a great deal of added security for Canadian investors seeking to make investments in the Chinese market.
