U.S. President Donald Trump has approved a landmark nuclear deal with Saudi Arabia, which would potentially pave the way for uranium enrichment on Saudi soil.

According to U.S. media reports, the Wall Street Journal, citing government officials, the deal would help the kingdom build a civilian nuclear programme.

The multibillion-dollar agreement is said to have a duration of 30 years, secure a key role for U.S. companies in building Saudi Arabia’s nuclear infrastructure and exclude other foreign competitors.

A central provision calls for U.S. companies to build a uranium enrichment facility in Saudi Arabia, provided a joint U.S.-Saudi study concludes that such a step is justified.

The Trump administration reportedly considers that this partnership would give the U.S. influence over the Saudi nuclear programme while ensuring it would not be misused for military purposes.
