Only Jewish, Zionist parties can join

Ha'Aretz is quoting (extracted from an interview with Israel Radio) Acting PM Olmert as saying, "Any Zionist, Jewish party is potential coalition partner".

Does that mean the Arab parties will not be brought into the coalition? Does that mean UTJ will not be brought in, as they officially do not accept Zionism? What about parties that decry Zionism as the cause of the problems, but have not necessarily denounced it, such as Meretz?
