PLAAF Instrumentation Standards

I came across a news article on a Russian (Aeroflot) 737-500 that crashed last September. The crash was ultimately ascribed to pilot disorientation, due to differences in flight instrumentation between Russian and Western aircraft:


This raised the question in my mind: which standard does the PLAAF use today? Obviously the MiG's that were supplied to China decades ago employed Russian instrumentation standards, with regard to how the artificial horizen is defined. But China's airlines, today, fly Western aircraft. So which standard is employed by the PLAAF now? Does anyone know?



Thanks in advance.
