The Saudis are now the only power to open Saudi Arabia’s US railway to Qatar.
A joint statement by the Saudi-Qatari Cooperation Council and the US State Department said the move was aimed at reducing trade barriers between the countries.
“This joint statement, which was issued on Monday, is the first of its kind in the history of Saudi-US relations and it is designed to further the joint vision of a Saudi-American economic and political partnership,” the statement read.
“In this joint statement Saudi Arabia will establish a permanent and solid economic corridor connecting the two countries in a way that benefits the Saudi economy and the Gulf region in the long term.”
Qatar has also been pressing for the Saudi Arabian railway to be opened to Qatar’s state-owned Doha World Airports.
Qatar has been a staunch ally of Saudi Arabia, with many of its citizens serving in the country’s armed forces.
Qatar’s Foreign Minister Sheikh Mohammed bin Abdulrahman Al Thani said the joint statement “proposes a path to open up the Saudi railway to the Qatar state-run airline and the Qatar-US joint venture in the interests of both countries”.
“This is a strategic and strategic strategic move,” he told reporters.
“It’s a step forward, a step towards establishing the Saudi Arabia-Qatar strategic partnership.”
Saudi Arabia and Qatar are technically neighbours, but their relations have been strained in recent years due to the two states’ policy of backing rival rebel groups in Yemen.
Last year, Saudi Arabia suspended the countrys $100bn (£74bn) arms deal with Qatar over its alleged support for the Houthi movement.
The decision prompted Qatar to suspend its oil exports to Saudi Arabia.
US President Donald Trump, who visited Saudi Arabia earlier this year, has repeatedly said he will not reopen the Saudi railroads until he gets a better deal from Qatar.
The US and Saudi Arabia have been negotiating a long-term deal that would see the two nations share oil and gas reserves in the region.
