The 69th General Conference of the International Atomic Energy Agency (IAEA) opened Monday in Vienna, focusing on the peaceful use of nuclear energy and technology and the urgent need to protect the global nuclear non-proliferation regime.

In a message delivered by Ghada Waly, director-general of the United Nations (UN) Office at Vienna, UN Secretary-General Antonio Guterres said the IAEA plays a vital role in ensuring nuclear science and technology are used solely for peaceful purposes. "Together, we can ensure that these tools advance development and safeguard humanity," the message said, urging continued efforts to eliminate the threat of nuclear proliferation.

IAEA Director General Rafael Grossi told the conference it is convening at a pivotal moment, citing terrorism, armed conflicts and the erosion of nuclear norms amid widening global inequality. He said he had informed the UN Security Council that the global nuclear non-proliferation regime is under significant strain and requires protection.

More than 2,500 participants, including representatives of IAEA member states, international organizations and non-governmental organizations, are attending the meeting, which runs through Sept. 19.

Delegates will review the agency's 2024 Annual Report and 2026 budget and discuss issues ranging from nuclear science and applications to safety, security and safeguards in Ukraine, the Middle East and the Democratic People's Republic of Korea.
