Reality check: You were not involved in the project and you definitely do not know what the Chinese government wants or needs. Stop making shit up as you go.
I would love to see a source on this one, but frankly it sounds farfetched. I can't find any record of a contract to upgrade KC-135, which would frankly be odd anyhow since the AF is buying a new tanker. Further, I can't find any evidence of an espionage prosecution against a Boeing employee or subcontractor employee in any tanker program. This seems like a fiction made up entirely for an HN audience.
