In a further attempt to distance itself from the former army commander, Field Marshal Sarath Fonseka, Sri Lanka's Leader of the House said this week that Mr Fonseka's views were personal and not that of the government's.
"The statement made by Fonseka was his personal opinion and not that of the government," Mr Lakshman Kiriella told parliament, the Sunday Leader reported.
The foreign minister would be making a detailed statement in two weeks, Mr Kiriella reportedly added.
Last week, the former military general Jagath Jayasuriya was forced to flee Brazil after human rights organisations filed lawsuits against him over his role in committing war crimes during the final stages of the armed conflict in Sri Lanka.
Mr Fonseka responded to the incident by saying he was away that crimes were committed under Mr Jayasuriya's command and he was willing to stand as a witness.
Mr Jayasuriya has rejected the allegations as "baseless".
Several Sri Lankan politicians have condemned Mr Fonseka's comments as traitorous.
