Foreign Minister of Switzerland Didier Burkhalter said that the situation in Karabakh had improved after the escalation in early April due to the efforts of Moscow, RIA Novosti reported.

The present situation in Karabakh is an important and serious matter, he said.

Thanks to the efforts of Russia the situation has calmed down a bit, but nevertheless, the region remains difficult, and there is still danger of escalation. Structured process of negotiation and dialogue  is necessary in order to solve this matter, he said after the negotiations with his Russian counterpart Sergey Lavrov .
