Konstantin Totsky said Jaap de Hoop Scheffer will arrive in Moscow in late June, but his visit will not be totally official as it will be held as part of festivities in Moscow and St. Petersburg to celebrate the anniversary of the Council.
"A schedule of [Russian] President [Vladimir Putin] is currently being coordinated and finalized, but we expect the meeting between the secretary general and the president to go ahead June 26," Totsky said during a Brussels-Moscow TV link, adding that "we expect no breakthrough decisions from this meeting."
NATO's reluctance to ratify the re-drafted Conventional Forces in Europe Treaty (CFE) is currently a key source of tension between Russia and the Western security alliance.
Putin earlier said Russia could withdraw from the Conventional Forces in Europe treaty, arguing that the pact had not been ratified by any NATO member states. NATO members have demanded that Russia first withdraw from Soviet-era bases in Georgia and Moldova under previous agreements.
The original CFE treaty, signed in 1990 to reduce conventional military forces on the continent and amended in 1999 in Istanbul in line with post-Cold War realities, has so far only been ratified by Russia, Kazakhstan, Belarus, and Ukraine.
