The United States and its allies continue building the global missile defense system, the Russian president said.
"Moreover, unfortunately, they are not taking into account either our concerns or proposals for cooperation," Putin added.
Russia has been assured on many occasions that the European segment of the US missile defense shield is developing in the wake of a threat from Iranian ballistic missiles, the Russian president said.
"However, we know that the situation with the Iranian nuclear problem has been settled and the relevant agreements have been signed. Moreover, they have been approved by the relevant parliaments. Nevertheless, the work on anti-missile defense systems is continuing," Putin said.
Therefore, the references to the Iranian and North Korean nuclear threats are only a cover for the US true plans, the Russian president said.
"And the US true goals are to neutralize the strategic nuclear potential of other nuclear states, except the United States and its allies, first of all, the nuclear potential of our country, Russia. Hence the desire to get decisive supremacy with all ensuing consequences," Putin said.
"We have said on many occasions that Russia will take all necessary measures to strengthen the potential of its strategic nuclear forces," the Russian president said.
