Summing up the outcome of the Berlin summit, the Irish Times claims that only moderate progress was made toward a durable ceasefire. The conference succeeded in bringing together the two warring factions and the various international powers backing them. That this seems to be the only achievement shows the extent to which the strategic interests of those key powers have become enmeshed in the conflict.
If anything came out of the conference, it is the general acceptance of the need to enforce the arms embargo and to find a political solution. However, the summit did not end with a ceasefire, rather only an agreement to appoint five people from each side to advance permanent ceasefire talks. One of the major challenges will the lack of leverage the EU and US have, especially as Russia an Turkey have increased their involvement.
