German Foreign Minister Frank-Walter Steinmeier said after a four-party ministerial meeting in Berlin on Wednesday that the foreign ministers of Germany, France, Ukraine and Russia have managed to work out a number of measures to achieve a truce in east Ukraine.

At today's talks the parties managed to agree a package of measures which cumulatively will lead to a reliable mutual truce in east Ukraine, the German minister said.

In addition, Steinmeier said that the meeting participants had supported the idea of sending Ukrainian border guards and OSCE observers to Russian checkpoints.

"We welcome Russia's readiness to ensure access for Ukrainian border guards to border points, and we ask the OSCE to also use [the possibilities of] its observers at these checkpoints," he said.

Steinmeier also said that the talks on the contact group on Ukraine would continue this week.

The ministers who have assembled here have backed the decision to return to the contact group's negotiations which should be held before July 5, he said.
