President Donald Trump will raise the possibility of setting up U.S. and Russian cooperation on easing the Syria conflict when he fulfils his Russian counterpart in Hamburg, according to a statement from Secretary of State Rex Tillerson.

Tillerson's statement — coming merely two days before Trump and Putin meet in Germany — reflects a U.S. determination to avoid getting too profoundly embroiled in maintaining the peace in Syria while also signaling a willingness for improved ties with Russia, which entered the Syria conflict in 2015 on behalf of the members of Syrian President Bashar al Assad. It's also the most detailed description yet of a topic the two leaders will discuss.

Russia bears primary responsibility for providing for the needs of the Syrian people and for ensuring that none of Syria's warring factions take territory liberated from the terror group, Tillerson said in the statement. Russia also has an obligation to ensure that Assad's regime doesn't employ chemical weapons again, he said.

“The United States and Russia certainly have unresolved differences on a number of issues, but we have the potential to appropriately coordinate in Syria in order to produce stability and serve our reciprocal security interests, ” Tillerson said.

The initiative bears echoes of a proposal circulated under President Barack Obama, when Secretary of State John Kerry and his Russian equivalent, Sergei Lavrov, tried — and ultimately failed — to establish a so-called Joint Implementation Group aimed at easing the conflict enough to pave the way for negotiations for a permanent resolving. Tillerson's statement, while lengthy, no further details of what he called ” a topic the president will create in his meeting with Russian President Putin .”

U.S. officials, including Brett McGurk, the U.S. envoy for the coalition to fight the Islamic State, have been quietly meeting with Russian counterparts for weeks to lay the groundwork for such cooperation. The Wall Street Journal reported June 9 that the administration was speaking with Russia to set up a de-escalation zone in southwest Syria.
