Russia says it thinks the top threats to its future security will come from NATO expansion and rivalry over energy resources.

The Kremlin on Wednesday unveiled its new National Security Strategy, outlining its priorities through the year 2020.  The policy paper was signed by Russian President Dmitry Medvedev. 

It says Russia cannot rule out the use of military force to "solve emerging problems" around the competition for energy sources.

The document says Moscow hopes to build "an equal and full-fledged strategic partnership with the United States," but criticized U.S. plans for a missile defense shield in Europe.

The new security strategy says Russia views any expansion of NATO to its neighboring countries to be "unacceptable." 

That remark is likely aimed at Georgia and Ukraine, which have sought to join the alliance over Moscow's objections.
