I am afraid that is not so.SMIC's behavior is actually questionable. As a publicly traded company,it is obliged to reveal the technical progress and detailed revenue source to public and shareholders.
Not long ago many semi-conductor companies such as Samsung were forced by US department of commerce to reveal who is their customer and the volumes of each. If such information is obligatory as a publicly trading company, why did the US government need to force it out? Samsung actually made a protest by referring such information as being "commercial confidential".
I also read my own (western) companies' quarterly report, we never say any technical details of what we are doing, or where we are in the progress. We may say "we increased our revenue by x% in market region y", we never say "we sold x number of things to customer y in country z".
