The HNS leader pointed to data which show that eastern Croatia is among the least developed regions in Europe.
The HNS advocates a fair society, which means good health care, education and a development-generating economy, Pusic said, adding that a fair society was also a corruption-free society.
The HNS will focus on these topics when it joins the election campaign.
Asked to comment on the coalition between the Peasant Party (HSS) and the Social Liberals (HSLS), Pusic said that her party was open to pre-election agreements on post-election cooperation with the two parties.
