On March 12, Iran's foreign minister said on Wednesday that an Arab country would deliver Trump's letter to Iran. US President Donald Trump said in an interview program clip broadcast on March 7 local time that he had sent a letter to Iran's Supreme Leader Ayatollah Ali Khamenei on the 6th, hoping to negotiate with Iran on the issue of nuclear weapons. However, Iranian media reported Trump's remarks earlier, but Khamenei's office did not confirm receipt of any letter.
