Moscow: Russian Foreign Minister Sergei Lavrov said on Wednesday that the United States was increasingly receptive towards Moscow’s position on the conflict in Syria.

Lavrov referred to comments by US Secretary of State John Kerry after military talks restarted between Washington and Moscow on Syria, where a war shows no signs of abating after four and a half years.

A Russian diplomatic source said on Wednesday that Moscow sees a growing chance to reach international agreement on fighting terrorism in Syria and resolving a conflict which has killed a quarter of a million people,

Diplomacy has so far failed to find a solution to the crisis, now in its fifth year, with international powers supporting rival sides and unable to overcome their differences over the fate of Syrian President Bashar Al Assad.

With Al Assad facing increasing pressure from Daesh and Western-backed rebels, Moscow has stepped up support for its long-time ally at the same time as it pushes a new diplomatic offensive on Syria.

It has increased arms supplies to the Syrian army and increased its military presence inside Syria, drawing warnings from Western nations — which oppose Al Assad — that it was destabilising the situation further.

It is not clear what agreement could be reached on the main sticking points in the conflict, but the Russian diplomatic source said the growing threat posed by Daesh was driving new international efforts for a deal “Moscow now has an optimistic view of chances for a settlement on Syria and uniting efforts to combat [Daesh],” the source said.

The drive may culminate later this month when world leaders meet in New York at the annual UN General Assembly summit.

Syria is also the key theme in Russian President Vladimir Putin’s talks this week with Israeli Prime Minister Benjamin Netanyahu, Palestinian President Mahmoud Abbas and Turkey’s Tayyip Erdogan.

Moscow and Washington restarted talks between their defence officials on Syria last week after a long pause in any such contacts amid chilly bilateral ties over another conflict — Ukraine.
