From the declassified documents obtained by Canadian journalist, Stanley Tromp: http://www3.telus.net/index100/records2
Soviet Deputy Foreign Minister Ivan Aboimov’s comments on 24 December 1989 to the US Ambassador to Moscow regarding renunciation of the “Brezhnev Doctrine” have previously been reported (sometimes using different phraseology, but with the same general content) in other fora: see, for example, https://www.wilsoncenter.org/sites/default/files/CWIHPBulletin10_p5.pdf ), but here one can see the original exchange:
“In response to the Ambassador’s direct question, Aboimov once again strongly reiterated the Soviet Union’s determination not to intervene militarily in Romania’s internal affairs, noting in a clear reference to Panama that ‘We have given the Brezhnev Doctrine to you, with our compliments.'”

What has not been reported previously are Aboimov’s comments with regard to who was the cause behind the continuing bloodshed in Bucharest and the rest of Romania:
“5. With regard to the Soviet Trade Mission personnel [two of whom had allegedly been wounded per paragraph 2], Aboimov said that the apartment building where many of the Mission’s personnel lived had been the scene of serious fighting yesterday. “Terrorists” (by which Aboimov clearly indicated he meant Securitate) had actually been in the building at one time. There was heavy shooting and the building itself was on set on fire. The shooting continued until midday, when the Soviet Embassy managed to evacuate Trade Mission personnel and their dependents from the building to Embassy grounds. Two persons were lightly wounded.” [For a similar incident, suffered by British personnel, see https://romanianrevolutionofdecember1989.com/resedinta-ambasadorului-britanic-tvr-si-teroristii-updated-w-british-foreign-office-records/ )

“6. Aboimov said the security situation around the Soviet Embassy itself was not good. Serious firefight had erupted for one or two hours yesterday near the Embassy when a “nest of terrorists” was wiped out by Government forces…”
