Switzerland said on Tuesday it was ready to assist diplomatic efforts to end North Korea's nuclear programme after condemning the isolated nation's latest nuclear test.
"This test violates UN Security Council resolutions, represents a threat to peace and security in the region and goes against the efforts of the international community in terms of nuclear non-proliferation," the foreign ministry said in a statement.
But it added: "Switzerland is convinced that a way out of the Korean peninsula’s nuclear and security problem can only be found within the framework of a process of diplomatic negotiation."
The ministry said Bern supported ongoing six-party talks on denuclearisation involving the two Koreas, China, Japan, Russia and the United States.
Switzerland is "ready to respond to any request that could contribute to the efforts to promote stability and peace on the Korean peninsula", it said.
North Korea has a special link to Switzerland -- the communist nation's leader Kim Jong-Un attended secondary school near Bern, without revealing his true identity.
