Like the EU, the Swiss government said it would impose an embargo on arms and on equipment used for internal repression.
"The new edict on measures against Syria includes an embargo on military assets and equipment that could be used for internal repression," said the Swiss Economy Ministry in a statement.
"It also includes financial sanctions and travel restrictions on 13 people from the Damascus regime," it added.
The ministry said that through the new sanctions, "Switzerland is joining sanctions announced on May 9, 2011 by the European Union against Syria."
"These restrictive measures were decreed due to the violent repression that the Syrian army and security forces have exerted over about two months to suppress the peaceful demonstrations of the population."
More than 850 people, including women and children, have been killed in the unrest and at least 8,000 arrested, according to rights groups.
