.The Saudis had expected to sign a nuclear agreement during U.S. President Trump's visit to Riyadh last month, but the Americans decided to hold off due to the talks with Iran.The Saudis will resume their push for a domestic nuclear program if and when a deal is reached with Tehran, the source said.“This is a very sensitive issue and if Iran is allowed to enrich uranium on its territory, the Saudis will demand the same,” the source stated. If Iran is allowed to continue enriching uranium, and the Saudis remain without a nuclear program, it will severely impact U.S.-Saudi relations, and the Saudis will seek cooperation on the matter with China, the source added.
