I was recently watching Sneakers (which Len Adleman advised on their "cryptography" sub-plot), which included a line along the lines of:
[Some hardware that ostensibly breaks American cryptography] doesn't work against Russian codes.
The speech that Adleman advised on seems vaguely like a description of a more powerful Number Field Sieve , so this would be consistent with Russia having standardized something like McEliece. Of course, I doubt they have done this, but in thinking about this I realized I have no clue what they have standardized, and therefore no clue if this was a plot hole, or excellent writing.
This leads to the broader question: Are there cryptosystems that have not been widely adopted in the West, that have been standardized by other major countries?
I'll include a handful of examples that I am aware of:
- The Lattice-based KEM LAC was recently chosen in China's variant of the NIST PQC competition.
- There are the Russian block ciphers GOST, and on Kuznyechik.
In this question I am mostly interested in historical example though (so of the above, mostly interested in GOST). Are there other well-known examples? I would especially be interested in asymmetric schemes, given the motivation to better understand Sneakers.
 Funnily enough, this came out ~ 1 year before the general number field sieve was published, but Adleman was not on that paper.
