Plans for a vast AI data hub in the UAE have raised security concerns in Washington due to the country's close ties with China.
The $100 billion Stargate UAE campus, aims to deploy advanced US chips, but US officials are scrutinising potential technology leakage risks.
Although the Trump administration supports the project, bipartisan fears remain about whether the UAE can safeguard US-developed AI and chips from foreign adversaries.
A final agreement has not been reached as both sides negotiate export conditions, with possible restrictions on Nvidia's hardware.
The initial phase of the Stargate project will activate 200 megawatts of capacity by 2026, but the deal's future may depend on the UAE's willingness to accept strict US oversight.
Talks over potential amendments continue, delaying approval of what could become a $500 billion venture.
