In the page that you linked, it states that he wants to implement a measure that enforces minimum 51% participation by the state in all natural resource exploitation activities on Romanian territory.

While this can be viewed as a left-wing policy, it can also be a form of economic nationalism.

As far as I understand, he gets classified as far right [1], because of his ultranationalist and ultraconservative views.

The parties that declared support for him [2][3][4], after the first election round, have similar views.
