ZURICH—The Swiss government detailed Wednesday further measures designed to prevent the country from being used by Russia to bypass sanctions imposed earlier this year by the European Union over the crisis in Ukraine.

The Federal Council, Switzerland's cabinet, said five Russian banks would be required to get authorization to issue new long-term financial instruments. The Swiss subsidiaries of the banks, however, are exempt from the measures as long as they aren't acting on behalf of their parent banks.

The cabinet didn't name the five Russian banks. In July, the European Union sharply reduced the ability of state-controlled banks, including Sberbank and VTB Group, to raise capital on European markets.

The cabinet also barred Swiss financial intermediaries from entering into new business arrangements with 11 Russian and Ukrainian people and businesses. The cabinet didn't specify the names added to the list.

It also expanded the ban on exports of military products or products that can be converted to military uses. It will also vet the export of goods used in oil and gas extraction projects in Russia.
