Russia has not shelved plans to deploy missiles near Nato countries despite a US rethink of its missile defence plan.
President Barack Obama's decision last week to scrap a land-based missile defence system was welcomed by Moscow.
Russia had threatened to deploy short-range Iskander missiles in the Russian enclave of Kaliningrad, which borders Poland and Lithuania, if the US refused to drop the plans.
The Kremlin always said Russia would only deploy the missiles as a counter-measure if Washington went ahead with its missile shield.
