Secretary of State Marco Rubio said Saturday that the United States is reviewing a Turkish proposal for a partial ceasefire in the Black Sea that would allow grain shipments to resume safely, speaking at a news conference on the sidelines of the G20 foreign ministers' meeting in Atlanta.
"We are studying proposals that were given to us by Türkiye a week or two ago, and we'll continue to evaluate that work," Rubio said. "We would like to achieve that. It may not end the whole war, but it could at least resolve one particular dimension of it."

"Not a new issue"
Rubio noted renewed interest in using the Black Sea to meet global grain needs and recalled Ankara's earlier role. "Türkiye, for example, made a sustained effort in this direction in the past, and at one point an agreement was even reached, but that agreement later broke down," he said, referring to the 2022 grain deal.
He stressed the urgency of the issue, particularly for Africa, and said the energy dimension should not be forgotten. Asked when a deal could happen, Rubio said he could not give an estimate.
Talks with Moscow and Kyiv continue
Rubio said Washington remains in contact with both Russia and Ukraine on ending the war, adding that the U.S. speaks with Ukrainians at least as often as with Russians. He argued that keeping channels open with Moscow matters given the risk of escalation and Russia's large nuclear arsenal.

On Iran, Rubio said President Donald Trump prefers a diplomatic solution but that a military option remains available, adding that U.S. Central Command continues to protect commercial ships passing through the Strait of Hormuz.
