Anwar Gargash, United Arab Emirates Minister of State for Foreign Affairs, said Thursday that Gulf states should be included in proposed treaty negotiations with Iran over its ballistic missile program and regional behavior. "It is essential that the Gulf Arab states be a party to the proposed negotiations. It is prudent for Tehran to avoid sanctions and to take these proposals seriously," Gargash tweeted. His tweet came after Brian Hook, US special envoy for Iran, said on Wednesday Washington is seeking to negotiate a treaty with Iran to include Tehrans ballistic missiles and its regional behavior. Iran has rejected US attempts to hold high-level talks since President Donald Trump tore up the 2015 nuclear deal between Tehran and six world powers earlier this year.
