Because missile guidance technology is a little more sensitive than the iPhone 8's screen dimensions. Because the specifics of the US space surveillance and communications network isn't something you share with anyone but the closest of strategic partners. Should china decide one day to join the club, to participate openly in defense projects and initiatives, then perhaps. When they allow US officers to serve on their ships and in their bases, as Canada/US/Australia/UK officers do in the west. When they allow US warplanes to fly in their airspace. When they allow Canadian ships to ply their waters without escort. Then perhaps. But that won't be for at least another generation or two.

Neither of which is in any way relevant to the civilian space program.

Exposure to America's space program could provide China with access to dual-use technology that they don't currently possess. Look into the Loral Space Systems controversy from 1996. From wikipedia:

Loral was accused of transferring technology to China in 1996. The incident arose as a result of an investigation into the launch failure of Intelsat 708, a Space Systems/Loral–built satellite. In a 2002 agreement with the State Department and Department of Justice the company agreed to pay $20 million in fines to settle the matter and to improve its compliance procedures. In the agreement Loral officials neither admitted nor denied the government's charges, but Loral executives acknowledged "the nature and seriousness of the offenses alleged by the department in the draft charging letter, including the risk of harm to the security and foreign policy interests of the United States", and stated that they wished to make amends through the payment of restitution. Schwartz subsequently released a statement accepting "full responsibility for the matter" and portrayed the incident as an error by a single Loral employee.

Far from being a tour-de-force of Chinese espionage, this rocket technology leak apparently happened because a Loral employee accidentally sent a single internal Loral post-mortem document by fax to their Chinese partners. Its almost impossible to keep secrets when there's close business cooperation like this; accidents happen.

If it's that easy to do it accidentally, I rather suspect China's intelligence services have it already covered via compromised employees and hacked servers.

[CountSessine]

Not in that case, no. The document apparently was a post-mortem on a failed satellite launch, that said something of the sort, "the launch failed because the Chinese engineers haven't begun doing so-and-so with technology XYZ as we have." The fact that the launch had failed in the first place suggested that the Chinese did not yet appreciate the importance or realize the existence of technology XYZ yet.

[ceejayoz]

Right, but that was in 1996.

In 2016? If Snowden and Manning can walk off with what they did, I can't imagine more subtle agents aren't siphoning off much, much more.

[CountSessine]

Ah - yes. My mistake - I misunderstood you.

[riffraff]

OK but what about Russia?

And what part of "you can send astronauts and modules to be part of the ISS" would expose American missile guidance systems to the Chinese?
