No need for that. Just plant people in the research team. Friendly and unfriendly countries have been doing that for decades (There weren't just Russian spies at Oak Ridge, etc)
Of course if you're spying on your friends you tend to need to be a bit more circumspect about how you use the information you've gathered, but the point remains.
