The department, in a statement today, said the two men will talk about how to end fighting between Ukrainian troops and Russian backed separatist rebels.
It added that on Syria, Tillerson "intends to discuss efforts to de-escalate violence, provide humanitarian assistance to the Syrian people, and set the stage for a political settlement of the conflict."
Russia is a key ally of Syrian President Bashar al-Assad.
But the meeting has now been moved to the US capital.
