Re: How significant are the Russian Military Scientists in China military developemen
Not sure how much contributive they are, considering how much of the Chinese defense industry is actually concentrated on the east and south of China. For example, even though Huludao is in the north in Heilongjian (Manchuria) building nuclear subs, all the subs are designed in Wuhan, which is in the south, central China, where the Songs and Yuans are built. The defense electronics are concentrated in Chengdu and in Nanjing. The radars and stuff you see on the KJ-2000 to the 052C for example, came out from Nanjing, which during imperial times, is the "summer" capital of China.
Chengdu is of course, where the J-10 is built. The JH-7As and H-6s are built in Xian, which is in the west of China, north of Tibet. Except for the 051 series, much of the Chinese ships, including the 053H Jiangweis, the Jiangkais, the 052 series including the 052B and 052C, are designed and built in centers in Shanghai and Guangzhou.
The "Russian" proper of China, which is Heilongjian/Manchuria, covers cities like Dalian (Russian name: Daly), Harbin, and Lushun, which used to be Port Arthur and the major station of the Russian Pacific Fleet before they lost to the Japanese at the turn of the 20th Century. Dalian is now a major shipbuilding facility and this is where the 051 series were built and where the Varyag is now sitting. Harbin's most famous defense industry contribution, are helicopters, and despite not sitting far from the Russian border in the Amur river, those helicopters are of French design, the Z-8s an Z-9s. Ironically, when the Mil-171 is licensed to be assembled in China, it went to a firm as far away from the Russian border as you can imagine---in a company in Chengdu.
And of course, there is Shenyang, former capital of Manchuria, and its most well known defense contribution have been aircraft, like the J-5/6/7/8 fighters, and most importantly the J-11s. Shenyang is also a center of gas turbine development.
Tanks, guns, fighting vehicles, you know the army stuff, tend to be produced by industries in the north, such as the aptly named NORINCO (Northern Industries Corporation) famous for its guns, like the Type 95, and the CNGC (China Northern Group Companies) which actually built the ZTZ-99. However these firms are in the Beijing and Inner Mongolia areas.
If Russian or former Soviet Union (can't say all are Russian) scientists and engineers are working in China, they wouldn't be stuck in just Manchuria.
