Matvienko claimed the decisions of international courts were increasingly being used as an instrument of political, economic pressure and interference in Russia's internal affairs.

"As an attempt to interfere, we can consider the initiatives to create an international tribunal in the case of the crash of the Malaysian Boeing in Donbas.
