God damn debating with you people is useless sometimes.
My second paragraph is meant to show a possible other explanation why the Chinese didn't want foreigners snooping around their bio labs: in my belief the same evasiveness the Chinese has/had would apply to the USA if China wanted to visit and have unlimited access (for a thorough investigation) of American bio labs.
And I'm not talking about whether American journalists would be arrested. I'm just talking about the evasiveness about the labs.
