"What we are trying to achieve before there is an international agreement is not to change the scope of the mandate and leave it to the Geneva conference to find a mechanism for South Ossetia and Abkhazia," Alain Le Roy said.
Russia has said the Security Council may not discuss extending the mandate of the United Nations Observer Mission in Georgia (UNOMIG), which expires on October 15, without hearing from all parties to the conflict.
Russia recognized South Ossetia and Abkhazia as independent states on August 26. Only Nicaragua has recognized the republics since then, although Belarus may follow suit later this month.
The UN, the EU, and the OSCE are to meet in Geneva next month to decide on an international mechanism to end the conflict between Georgia and Russia.
The current UN force, with 130 military observers and a small police force, has been mandated to monitor a ceasefire between Abkhazia and Georgia.
