PM May agreed with Saudi Crown PRince Mohammed Bin Salman on the importance of full and unfettered humanitarian and commercial access, including ports access.
Later on Wednesday, the Saudi Arabian and British foreign ministers held a joint press conference to lay out agreements between the two countries.
The UK and Saudi Arabian FMs agreed to monitor the navigation routes in preparation of the reopening of the ports in Yemen.
UK's Boris Johnson said that the UK has called for an international meeting to discuss with Saudi Arabia a political solution in Yemen. He said that the world understood Saudi Arabia's right to protect its borders.
Saudi Arabia's Adel Al-Jubeir said that Saudi Arabia supported the transitional process and political dialogue in Yemen and the war in the country was imposed on Saudi Arabia, but that the Kingdom will continue to provide humanitarian assistance to Yemen after the war's conclusion.
He also added that Riyadh and London agreed on the necessity to deter Iran and stop its support terrorism, while Johnson said Iran was playing a disruptive and dangerous role in Yemen and destabilizing the region.
Meanwhile, Al-Jubeir said that there were great opportunities for cooperation with the UK to achieve the Crown Prince's Vision 2030 in Saudi Arabia.
