"Investigators act in a very one-sided manner, they ignore important materials presented by the Russian side, while they willingly, without any checks, trust the Ukrainian representatives", Shulgin said at a briefing.
The Russian diplomat described this policy as "double standards".
He also slammed media reports about alleged threats that families of the MH17 crash victims face.
"Just last week, a publication emerged in Dutch media claiming that someone was threatening lawyers of the families of victims of the Malaysian Boeing crash. Allegedly, some people in sunglasses are watching these lawyers, are spying on them. Well, this statement is absolutely groundless, it is just evidence-free", Shulgin said at a briefing.
Flight MH17 of Malaysia Airlines crashed on 17 July 2014, in eastern Ukraine while en route to Kuala Lumpur from Amsterdam. All 298 people on board were killed. Kiev and the self-proclaimed republics in Ukraine's eastern Donbass region, where the plane was shot down, have blamed each other for the incident.

/ The investigation into the MH17 crash is being conducted by Dutch prosecutors and the Dutch-led Joint Investigation Team (JIT). The international group of investigators claims that the plane was downed by a Buk missile belonging to the Russian armed forces, something Moscow categorically denies.
Russia conducted its own investigation and said it had provided the JIT with evidence, including radar data, showing that the plane had been shot down by a Ukrainian Buk missile. However, Moscow was denied any access to the probe.
