"The Federal Department of Economic Affairs has made amendments to the list of individuals attached to the directive on the prevention of the busting of international sanctions over the situation in Ukraine. Two individuals and four entities are included in the annexe", according to the department.
The department added that the sanctions became effective late on 15 October.
The sanction list has been expanded with the inclusion of CEO of Alexander Ganov of Grand Service Express railroad company and Leonid Ryzhenkin, Deputy CEO of Stroygazmontazh infrastructure company.
This decision also affected Lenpromtransproekt project company, the Directorate for the Construction of the Railway Line Berkatit-Tommot-Yakuts infrastructure company, the Crimea Railway enterprise and the Krymskaya Pervaya Strakhovaya Kompaniya insurance company.
The Swiss action followed on the heels of the EU decision, made in early October, to impose sanctions over Ukraine against two individuals and four entities.
The EU countries initiated aggressive sanction policy against the Russian Federation after it annexed the Crimean peninsula in 2014. The step has been considered by Brussels as a violation of international law and has served as a justification for Brussels unfriendly attitude towards Moscow.
Crimea reunified with Russia in 2014 following a successful referendum on the matter on the peninsula. While Western countries and Kiev have not recognised Crimea's new status and accused Moscow of meddling in Ukraine's affairs, Moscow has denied any interference claims and insisted that the referendum was carried out in line with international law.
