In an earlier interview with CBS, U.S. President Biden said he won't lift U.S. sanctions on Iran unless it shows commitment to JCPOA. What will be Tehran's response to Biden's proposal? Abbas Araghchi, Iranian deputy foreign minister, told CGTN anchor Wang Guan that the U.S. should act first. He said Iran is ready to quickly go back to full compliance to the JCPOA once all sanctions against the country are lifted.
