I would be suspicious. I live in Alaska and am pretty familiar with the seafood industry here. There is no Chinese presence in the processing sector that I am aware of and I doubt fish are being sent out to process in china. It is possible that they are catching AK salmon outside of the US 200 mile EEZ, which raises sustainability issues. Is it labelled MSC certified? (marine Stewarship Council). If not, then even more doubtful as to the provenance.
