On the agenda, she has had both the ceasefire and the humanitarian situation in eastern Ukraine.

A situation that she describes as very difficult.

"The conflict is one of the biggest threats to the European security order and the principles agreed upon by all OSCE participating States," said Ann Linde.

The first peace plan was written in 2014

The war in eastern Ukraine began in April 2014 when armed men took control of police authorities in Luhansk, Donetsk and Kharkiv.

The separatists, who are supported by Russia both militarily and economically, today control the area around Donetsk, Luhansk and a 150-kilometer-long part of Ukraine's border with Russia.

During this time, Russia has repeatedly sent troops into the area to assist the separatists.

The first peace plan, the Minsk Agreement, was signed in September 2014, a second agreement was signed in 2015. In principle, it states that ceasefire will prevail and that both sides will withdraw their heavy weapons.

No agreement has worked so far

The agreements have so far not worked.

More than 13,200 people have died as a result of the war, including several thousand civilians.

Today, Linde met with both Foreign Minister Dmytro Kuleba and President Volodymyr Zelensky to discuss what the OSCE can do for the peace talks.
