The United Arab Emirates' senior national security adviser met his Iranian counterpart in a rare visit to Iran on Monday in a diplomatic move aimed at overcoming their long-standing differences and increasing co-operation.
Sheikh Tahnoon bin Zayed Al Nahyan's visit took place days after Tehran and world powers broke off talks in Vienna aimed at salvaging Iran's 2015 nuclear pact, which Washington abandoned three years ago and reimposed harsh sanctions on the Islamic Republic.
Sheikh Tahnoon, who is a brother of the UAE's de facto ruler, Abu Dhabi Crown Prince Mohammed bin Zayed, discussed expanding bilateral ties and regional issues with Iran's top security official Ali Shamkhani, Iran's Nournews reported.
"Stability and security can only be established through continuous dialogue and cooperation between the regional countries," Shamkhani said, according to state TV.
"Improving economic, trade and investment ties are the main priorities of Iran's foreign policy."
