German Foreign Minister and OSCE Chairperson-in-Office Frank-Walter Steinmeier has praised the outcomes of a meeting between the Armenian and Azerbaijani presidents in Vienna, which dealt with efforts to settle the conflict over Nagorno-Karabakh, the OSCE said in a press release on Tuesday.

"I welcome the initiative by my colleagues from the Russian Federation, the United States of America, and France, the co-chairing countries of the OSCE Minsk Group, who held a meeting with the Presidents of Armenia and Azerbaijan on 16 May," Steinmeier said.

"I am encouraged by the renewed commitment that both Presidents have expressed to the ceasefire and to the peaceful settlement of the conflict, as well as their readiness to have a new round of talks in June," he said.

At the same time, Steinmeier expressed his concern about the situation in the conflict zone.

"I deeply regret the reported recent loss of life, and I urge the sides to respect the ceasefire in full," he said.
