Israeli Foreign Minister Israel Katz visited Abu Dhabi this week to participate in a U.N. climate conference, according to his office.

However, Katz met with an unnamed “senior UAE official” to discuss “regional issues and relations between the countries,” which currently do not have formal diplomatic relations.

The meeting centered on “the need to deal with the Iranian threat related to the nuclear issue, missile development, Iran’s support for terrorism in the region and the violence employed by Iran against the interests of the region,” according to Katz’s office.

The visit came as the International Atomic Energy Agency announced on Monday that Iran exceeded the uranium enrichment limit under the 2015 nuclear deal.

The two officials also talked about improving economic ties, including in the sectors of energy, water, agriculture and high-tech—all part of Israel striving lately to expand relationships with regional players.
