Crown Prince Mohammed bin Salman, Deputy Prime Minister and Minister of Defense, held talks in Paris on Tuesday with French President Emmanuel Macron on regional issues and other affairs of common interest. During a press conference at the Elysee palace, the two officials agreed on the need to curb Iran’s expansion in the Middle East. Prince Mohammed accused Tehran of supporting terrorism in the region and working on spreading its ideology instead of working for its people. For his part, Macron called for "greater efforts to limit Irans ballistic activity and regional expansionism". The two leaders were meeting at the conclusion of Prince Mohammed’s three-day official visit to Paris. "This strategic vision means reducing all the projects of expansionist political Islam which could feed other forms of terrorism and destabilize the region," Macron added. Addressing Yemen, they announced that a conference to boost humanitarian support for Yemen will be held in France during the summer. "Between now and the summer a joint conference will be held on Yemen to clarify what is being done and what needs to be done," Macron said. He also stressed the need for "respect for international humanitarian law". "We will continue to be extremely vigilant on this point," he said, while adding: "It is obvious that we will not tolerate any ballistic activity that threatens Saudi Arabia." Furthermore, Prince Mohammed said: “The Saudi-French partnership is very important, especially at this time.” Turning to the developments in Syria, Macron said a decision on whether to carry out military strikes on Syrian chemical weapons facilities would be made in the coming days after more consultations with the United States and Britain. "The third element is the red lines defined by France. These red lines, which are shared by other powers, have nothing to do with the discussions taking place at the UN Security Council." "In this context, we will continue exchanges of technical and strategic information with our partners in particular Britain and America, and in the coming days we will announce our decision." He said if there were strikes they would be aimed at the Syrian regime’s chemical facilities. “We do not want an escalation in the region,” he stressed. “We must focus on the humanitarian efforts in Syria in cooperation with the UN.” After a trip which has seen France and Saudi sign up for major cultural exchanges as well as discussions of war in the Middle East, companies from both countries signed draft deals worth a total $18 billion (14.5 billion euros). The memoranda of understanding cover sectors including petrochemicals, water treatment, tourism, health, agricultural and cultural activities, the French-Saudi business forum said in a statement.
