"Rather than dig itself deeper, US should abandon failed policies & return to #JCPOA (the 2015 nuclear deal)," Zarif tweeted.
The United States, who exited the pact last year and reimposed sanctions on Iran, on Thursday imposed sanctions on the Iranian construction sector and trade in four materials used in its military or nuclear programs.
"Subjecting construction workers to #EconomicTerrorism only manifests maximum failure of "maximum pressure”. US can sanction every man, woman & child but Iranians will never submit to bullying" Zarif tweeted.
