The bloc had previously been part of a Western-leaning coalition in the Supreme Rada - with the Yulia Tymoshenko Bloc and the Socialist Party - that collapsed giving way to the "anti-crisis" coalition led by pro-Russia Party of Regions, which nominated its head Viktor Yanukovych as prime minister.
Although former premier Tymoshenko has categorically ruled out working with Yanukovych, her arch rival and predecessor in the prime minister's chair, Roman Zvarych, a senior Our Ukraine member, was less unequivocal.
"We are ready for cooperation on condition the country continues its domestic and foreign policy line," he said.
Zvarych said Ukraine should continue working to join the World Trade Organization by the end of 2006 and the European Union, as well as maintain close ties with NATO and eventually join the alliance. Viktor Yushchenko has made these priorities since he won the presidency following the 2004 "orange revolution."
At home, Zvarych said the government should work to promote human rights, democracy, and reform the judiciary.
If these terms are accepted above all by the Party of Regions, which pledged to improve relations with Russia and make Russian Ukraine's second official language, Our Ukraine will be ready to discuss further membership terms in a new coalition, Zvarych said.
The pro-presidential faction had previously demanded the disbandment of the "anti-crisis" coalition of the Party of Regions, the Socialist Party and the Communist Party, which holds 240 seats in the 450-seat Supreme Rada, and a ban on the Communists from joining a would-be alliance.
Seeking to force the president to call new elections, the 124-seat bloc of Tymoshenko, Yushchenko's "orange" ally and previous premier-in-waiting in the first post-election coalition, withdrew from the Rada Monday.
Yushchenko, who is yet to approve the nomination of Yanukovych, can still use his power to dissolve the assembly, which failed to set up a coalition and form a government within 60 days since its first sitting.
