Presumably someone in the Chinese government ordered Google to lie about the institute's location. Why would the Chinese government do that if the institute was uninvolved?
Investigators ought to ask China who ordered it, and why. And ask Google the same thing.
I do feel a bit sorry for Google employees who'd be caught in the middle if this actually happens.
US government to Google: "Tell us about how China ordered Google Maps to help with the coverup. If you lie to the investigators, we'll send you to jail."
China government to Google: "When the US asks about the Google Maps coverup, lie. If you don't lie to the investigators, we'll send you to jail."
