According to this Wikipedia article, Marine Le Pen promised the recognition of Russian annexation of Crimea if elected as a president:
According to Russian media, Le Pen has promised to recognize the 2014 Russian annexation of Crimea (from Ukraine) in case she is elected President of France.
The cited link (original in Russian, Google translated) states that:
"Taking into account the historical realities, as well as a choice which was clearly expressed in the referendum on the accession [of Crimea to Russia], I, if elected, recognize Crimea Russian territory", - said the politician.
Political status of Crimea seems to be very complicated, as only a few United Nations members recognized Republic of Crimea and Sevastopol:
The following members of the United Nations have made statements about their recognition of the Republic of Crimea and Sevastopol as federal subjects of Russia: Afghanistan, Cuba, Kyrgyzstan, Nicaragua, North Korea Syria and Venezuela.
So, no EU countries recognize this new autonomous territory.
Question: is it possible for the President to decide the policy regarding recognition of a new state?
