Ukraine's governing coalition and opposition failed to start a round-table discussion because the leader of the pro-Russian Party of Regions, Viktor Yanukovych, had not showed up.
Mykola Tomenko, a top ally of would-be Prime Minister Yuliya Tymoshenko, said there was no point to the meeting without Yanukovych.
The Party of Regions began blocking the parliament last week as the new coalition planned a vote on naming Tymoshenko prime minister.
There is no indication when a new attempt will be made to start the assembly.
