The United Nations General Secretary Antonio Guterres has urged US President Joe Biden to waive the sanctions on Iran as agreed on 2015.

The UN Cheif appealed to lift the sanctions as per the Joint Comprehensive Plan of Action (JCPOA).

Guterres also urged the United States to "extend the waivers concerning the trade-in oil with the Islamic Republic of Iran, and fully renew waivers for nuclear non-proliferation projects." 

His appeal to Washington came amid talks to revive the JCPOA, under which Iran accepted curbs on its nuclear program in return for a lifting of many foreign sanctions against it. 

Washington withdrew from the deal in 2018 and reimposed sanctions on Tehran. In response, Iran gradually stopped implementing parts of its JCPOA commitments from May 2019.  

"I appeal to the United States to lift or waive its sanctions outlined in the plan," said Guterres, who also appealed to Iran to return to full implementation of the deal.
