Remember that Chinese embassy in Belgrade the Americans accidentaly bombed in 1999? :
Rumours have persisted throughout the past decade that the bombing of the Chinese embassy was not accidental at all. What with the close cooperation between Serbia and China at this time:

Hmm rumours huh somehow I suspect those rumours were mostly by people in China and Serbia, the reality is that people sometimes just cannnot imagine that anything the USA does could be a up ever. Russia, China or whoever is the new fella in a generals hat with sunglasses tend to see the world far more in terms of realpolitik they cannot imagine the other side does not to the same extent.

Sometimes it really is a mistake.

I doubt China needed any bits from a crash site though there well capable of stealing it from the USA.

Plus China has had what 20 yrs to try to design a stealth fighter since it was unveiled.
