In his brief answers to questions from reporters who were waiting for him while he was entering the Alpbach conference hall, Sanader said that he would not come back to the politics.
He also declined to comment on media reports implicating him in the scandal surrounding the Hypo Bank.
The former Croatian premier only said: "The dogs bark but the caravan moves on."
Sanader participated in a panel discussion on Bosnia-Herzegovina 15 years after the Dayton peace accords.
Apart from him, some of the other speakers were the international community's High Representative to Bosnia, Valentin Inzko, the Zagreb-based Vern university's head, Goran Radman and Kosovo Minister of Finance and Economy, Ahmet Shala.
When asked, during the panel discussion, whether in his capacity as the premier he could control commercial bank directors in Croatia, Sanader said that he had to hold talks with them but that he had not known what they had been doing and who they had been cooperating with.
