The Russians, , argued one Soviet MiG division would not be able to hold its ground, and then, insisted China build the four Soviet airfields simultaneously, and let North Korea construct the four airfields the Chinese needed.11 Soviet disapproval put the Chinese in a predicament. The Chinese Air Force had few engineering units able to undertake the task. With little engineering equipment available, progress on the project would depend on how much manpower could be mobilized. The Chinese leadership originally planned to involve two to three newly recruited divisions of the North Korean People's Army (KPA) in the construction of the airfields, and have the Chinese Air Force engineering units assist in hopes that the first airfield could be completed by the end of March. Although Kim Il Sung had agreed to cooperate, no North Korean soldiers were ever sent to do the job by that time.12 Soviet objections, furthermore, compounded the problem by insisting on the building of the four airfields at the same time which forced Beijing to employ combat troops to do so, a situation Peng was reluctant to accept.
Considering the Soviet Union's reaction and/or response, I can see that the Russians reacted quickly and effectively after the invasion in South Korea from the North Koreans.
