Reminds me of the US Embassy in Russia that was built, by Russians, who embedded thousands of spying devices within the building itself. It took 27 years to build, then debug the building.

It’s all part of the game it seems.

The US bugged the “toilet partitions” of the Russian embassy in D.C. during its construction[0] and the FBI built a tunnel under it for espionage purposes in the 80s[1].
