5G coding system was based on a technical paper by a Turkish prof on what's called polar coding. At the time the head of Huawei wireless, Mr. Wen Tong(?) ex Nortel guy, saw it on a tech journal, so he and Huawei put tons of money, ppl and resources into this and within 10 yrs Huawei had a huge success on 5G.
In articles by Spengler (Goldman) on atimes.com he sometimes/occasionally downplayed Chinese scientists' contributions, saying that over 50% are discovered by the 23 Huawei research centers around the world..anyway, you can't belittle either side, both Chinese and overseas ppl combined their knowledge and research.
A week ago when Mr. Ren mentioned about moving resources from Huawei USA to Huawei Russia, he said that Russia is a major theoretical center, and something that China is heading towards that level,too.
btw, stealth tech (f117 etc) was first described in mathematical modelling by a ussr scientist in a tech paper, then a Pentagon scientist saw that and further developed it lol
One picture. Russia's STEM graduates are nearly double the capita of the US.
