For the first time, the United States has been named as a threat to Russia's national security in the updated document signed by President Vladimir Putin.

The new report, dubbed "About the Strategy of National Security of Russian Federation,'' also designated NATO as an equal threat to Moscow's security, "due to the alliance trying to retain [its] dominance in global affairs,'' according to Fox News.

The new document reportedly replaces the 2009 version endorsed by then President Dmitry Medvedev, which made no mention of either America or NATO. It was signed by Putin on New Year's Eve, making it official policy.

The report states that in recent years, Russia has managed to increase its role in solving global issues and conflicts, which has caused a reaction from the West. "The strengthening of Russia happens against the background of new threats to the national security, which has complex and interrelated nature,'' it states.

The continuing policies that would heighten Russia's global standing will likely lead to "political, economical, military and informational pressure'' on Russia, it adds.

The document reportedly underscores the increasingly anti-Western rhetoric employed by Putin in the past two years, as relations between Moscow and the West have soured over the annexation of Crimea and war in east Ukraine.

The West claims that Russia has been instrumental in supporting rebels in east Ukraine, something Moscow has largely denied. Russia meanwhile criticises the West's position on Ukraine, accusing the U.S. and Europe of supporting an "anti-constitutional coup'' which it says "has led to a deep split in Ukrainian society and the emergence of armed conflict.''

Moscow also warns that Ukraine has now become a "long-term source of instability in Europe and on Russia's borders,'' the Financial Times reported.

Fox News said the document does not mention Syria where Russia recently began airstrikes against ISIS forces and anti-Assad rebels.

Assad, a Russian ally, has received military support from Russia in the civil war against U.S.-backed rebels and the Islamic State.
