Kerry and Russian Foreign Minister Sergey Lavrov are meeting today. They'll sit down at the residence of the Russian ambassador to France to go over Moscow's response to a US plan to de-escalate the situation as Russian troops continue to mass along the Ukrainian border.
US officials say the plan covers the disarmament of irregular forces, international monitors to protect minority rights, direct dialogue between Russia and Ukraine and Ukrainian political reforms.
Kerry and Lavrov have met several times in person and spoken by phone almost daily since the crisis began but have not yet been able to agree on a way forward.
