Sheikh Tahnoon bin Zayed Al Nahyan, the UAE’s top national security advisor, will visit Tehran on Monday to meet with key officials and explore ways to strengthen bilateral ties, according to a news site connected with Iran’s Supreme National Security Council.

The visit comes a week after negotiations between Iran and foreign nations started in Vienna to resurrect a 2015 nuclear agreement, relieve US sanctions on Iran, and put a halt to Tehran’s nuclear program expansion.

According to Nour News, Sheikh Tahnoon will meet with his counterpart, Supreme National Security Council Secretary General Ali Shamkhani.

Sheikh Tahnoon is the head of state investor ADQ and the brother of the country’s de facto ruler, Abu Dhabi Crown Prince Mohammed bin Zayed.

Last month, Anwar Gargash, the UAE president’s diplomatic adviser, stated that his country was “taking efforts to de-escalate tensions with Iran as part of a strategic decision towards negotiation and away from confrontation.”

The UAE remains highly worried about Iran’s behavior in Iraq, Syria, Yemen, and Lebanon, according to the Emirati ambassador.
