Russia and the United States cannot overcome all their differences during one meeting, said the Russian Foreign Minister Sergei Lavrov, reports  RIA Novosti.

"Rex Tillerson confirmed the readiness of Donald Trump, which he had stated in his telephone conversation with the President Vladimir Putin, to eliminate all artificial obstacles and overcome this difficult period. However, there are always issues in Russian-US relations, that will require coordination and solution. It is not possible to immediately overcome all the differences," Lavrov said after his meeting with the US Secretary Rex Tillerson.
