MOSCOW. Oct 29 (Interfax) - Moscow regrets that Ukraine is all but boasting about the fact that it has supplied Georgia with weapons, a high-ranking Russian Foreign Ministry official said.

"We have raised this issue in all international formats and regret that our Ukrainian partners are bragging about their violations," Russian Deputy Foreign Minister Sergei Ryabkov said in a report published in the Wednesday issue of Kommersant.

Ukraine is a signatory to a number of international documents regulating arms sales, Ryabkov said. "These include an OSCE document dating back to 1993, which regulates the passage of conventional weapons, and another OSCE document on firearms and small arms," he said.

However, in the case of Ukraine and Georgia, the matter involves heavy offensive weapons, Ryabkov said. "Moreover, Kyiv is not even denying the fact of passing them to Georgia right up to the conflict and for a long time before then," he said.

Ryabkov regretted that imposing international sanctions on Ukraine looks unlikely. "Sanctions are a UN Security Council prerogative, and all our attempts to impose an embargo on the sales of weapons to Georgia have encountered opposition from the countries covering up for the aggressor," Ryabkov said.

The same article quotes Russian Foreign Ministry spokesman Igor Lyakin-Frolov as saying, "I don't have information that Russia is conducting its own investigation on this account. We will wait for outcomes of an investigation by a Ukrainian parliamentary commission and, depending on them, will take these or those steps," he said.
