Georgia's neighbours and other countries in the region expressed concern about the crisis even before the resignation of President Eduard Shevardnadze.
An Armenian opposition leader warns there is a danger of the Georgian crisis spilling over to his country, where he says election irregularities are rife.
The following are quotes from regional leaders.
Azerbaijani President Ilham Aliyev:
Azerbaijani citizens are deeply concerned about what is currently happening in Georgia. Azerbaijan is supporting and will continue to support the legitimately elected head of the friendly and fraternal state of Georgia.
Armenian President Robert Kocharyan:
Political stability is necessary not only for Georgia, but also for Armenia and the whole region.
Armenian opposition National Democratic Party's Shavarsh Kocharyan:
The developments in Georgia show that the country's society and political forces will no longer tolerate dictatorship... [and] might result in a chain reaction in Armenia. People might start disturbances because there have been as many election irregularities in Armenian elections as in Georgia.
Ukrainian President Leonid Kuchma, head of the council of CIS heads of state:
The development of the situation in Georgia has raised great concern among CIS states. A range of Georgian political forces are prepared to grab power through unconstitutional means, which are categorically unacceptable for all democratic countries. CIS states call on all political forces in Georgia interested in independence and the territorial integrity of the country to return the process to democratic, constitutional channels and are ready to give Georgia everything necessary to help it achieve this aim. We have faith in the wisdom of the Georgian people and hope that peace and constitutional order will be restored.
Turkish Foreign Minister and Deputy Prime Minister Abdullah Gul:
"We have been monitoring all developments. We have been in touch with officials of both ruling and opposing parties. We have been expending efforts to lead them to a compromise. We want Georgia to overcome its problems with a compromise and to reach stability as soon as possible.
Sergey Shamba, foreign minister of Georgia's breakaway Abkhazia region:
We are keenly observing what is going on in Georgia, because we had an unpleasant experience when an unstable situation in Georgia led to aggression in 1992. Then too there was a revolution, and the authorities who came in directed their activities at Abhkazia. We must provide for all eventualities, although we hope the situation will resolve itself and perhaps they will succeed in overcoming this confrontation.
