On the record from State Department Spokesperson Jen Psaki:
In their conversation on Saturday, Secretary Kerry made clear to Foreign Minister Lavrov that the United States wants to see a cessation of Russian military advances in Ukraine including Ukraine’s Crimean Peninsula, a halt in the drive for annexation of Crimea, and the end of provocative steps to provide space for diplomacy.
The United States needs to see concrete evidence that Russia is prepared to engage on the diplomatic proposals we have made to facilitate direct dialogue between Ukraine and Russia and to use international mechanisms like a contact group to deescalate the conflict.
We are still awaiting a Russian response to the concrete questions that Secretary Kerry sent Foreign Minister Lavrov on Saturday in this regard.
Secretary Kerry made clear to Foreign Minister Lavrov that he would welcome further discussions focused on how to de-escalate the crisis in Ukraine if and when we see concrete evidence that Russia is prepared to engage on these proposals.
