During the last years I have encountered several cases when Russian classified documents are supposed to contain relevant information for some key events in Romania:
Romania's last king - some historians claim that the forced abdication from 1947 is far from being clear and Russians might have documents clearing things up
Romanian Revolution - also, some historians and analysts claim that Russia has documents that might shed some light on what really happened during Romanian Revolution (1989) when hundreds of persons were killed.
I am wondering if Russia has a clear policy on how this information is kept.
Question: What is Russian Federation policy for information declassification related to historical events within neighboring countries?
