Edit: since it appears no one can actually answer this question with an actual answer, and only down vote and troll, I think that probably means wikileaks does not make significant leaks from the military-industrial complexes of China or Russia.

Tibetan dissent in china, russians spying on their own people, ect. There's a few entries that contain multiple countries. I only skimmed the list.
For all of these reasons, it is much much less likely for any leaker out of China, Russia or Iran to leak to Wikileaks instead of someone else.
On the small chance you had, you still wouldn't give an organization with nobody that speaks your language the information as none of your neighbors have ever heard of their website. You would give it to a local journalism source.
So yes, Wikileaks does not make significant leaks from the military-industrial complexes of China or Russia. Anybody expecting them to has no clue what they are talking about.
In the US, you become a best selling author:

Our culture and protections(1A) allow an environment of leaks. Obama’s war on whistleblowers barely made a dent:
