"The UAE does not yet see a clear framework for the stability force, and under such circumstances will probably not participate in such a force," Emirati presidential advisor Anwar Gargash told the Abu Dhabi Strategic Debate forum.
The US-coordinated international force has been seen as likely to include troops from Egypt, Qatar and Turkey, as well as the UAE.
Last week, US President Donald Trump said he expected the force to be in Gaza "very soon", as a fragile ceasefire holds following two years of war. The oil-rich UAE is one of the few Arab nations with official ties to Israel after signing the Abraham Accords during Trump's first term in 2020.
