Russia's foreign ministry has said the delivery of the advanced surface-to-air missile system would be considered a provocative step.
Earlier on Wednesday, Mr Putin said he believed his country was not to blame for the war in Ukraine, adding both countries were "sharing a tragedy".
Since Russia invaded Ukraine on 24 February, the US military estimates that at least 100,000 Russian and 100,000 Ukrainian soldiers have been killed or injured, along with some 40,000 civilian deaths.
