Lavrov knew about the content of Trump's letter and did not agree with it

According to Ashura News, Noornews claimed in a tweet: "Lavrov's statements before delivering Trump's letter to Iran show that he was aware of the contents of the letter and did not agree with it. Is the opposition the reason for entrusting the mission of sending the letter to the Emirates and not Russia?" Moscow had previously welcomed mediation between Iran and the United States.
