Secretary Pompeo and Russian Foreign Minister Sergey Lavrov spoke by phone today. The two discussed issues and concerns related to Syria and the bilateral relationship. Secretary Pompeo reemphasized the U.S. commitment to the southwest ceasefire arrangement that was approved by President Trump and President Putin one year ago. He noted that it was critical for Russia and the Syrian regime to adhere to these arrangements and ensure no unilateral activity in this area.
