there was some confusion as to whether Qatar shared a border with the UAE, with maps commonly depicting a long Emirati panhandle touching Qatar. This treaty gave Saudi Arabia access to the Khor Al Adaid, thereby removing any possibility of Qatar sharing a border with the UAE.

, supported by Britain, succeeded in removing the Ottomans from much of the Middle East; in the period following this, Ibn Saud expanded his kingdom considerably, eventually proclaiming the Kingdom of Saudi Arabia in 1932. Ibn Saud refused to recognize the Anglo-Ottoman lines and lay claim to large parts of the eastern Arabian hinterland (the so-called ‘Hamza line’).

On 25 November 1935 British officials met with Ibn Saud in an attempt to finalize a frontier between the new kingdom and their coastal protectorates, including Qatar. The conference proved abortive, however, and the issue remained unresolved.
According to a British document written in 1936, the prime cause of friction in the territorial dispute revolved around where Qatar's south-west borders should end. The rulers of both Qatar and Saudi Arabia claimed that their control of the Dohat Salwa area had historical precedent, however, Ibn Saud claimed that the Sheikh of Qatar had previously ceded this territory to him, to which the Sheikh denied. The letter stated:
The conference proved abortive, however, and the issue remained unresolved.
In 1955, following
an attempt by Saudi Arabia to assert its control over the
Buraimi Oasis on the
Oman–Trucial States border, Britain stated that it would unilaterally use a slightly modified version of the 1935 'Riyadh line' henceforth.
A border treaty between Qatar and Saudi Arabia was made in 1965, though the precise terms of its implementation was a long-standing point of contention between the two.
In September 1992, tensions arose when Saudi forces allegedly attacked a Qatari border post, resulting in the death of two Qatari soldiers and the imprisonment of a third. According to Saudi Arabia, the attack was precipitated by Qatar moving its border post of Al-Khufus about south from its previous location during the
Gulf War

A border agreement was reached between the two parties in 1999, and the final treaty was signed in 2001.
Following a
severe deterioration in
Saudi–Qatar relations in 2017 the border was shut. In June 2018 Saudi Arabia announced that it is planning on constructing the long
Salwa Canal running along the Saudi side of the Salwa Border Crossing at a cost of $745 million. The canal is set to physically separate Qatar from its only land border and effectually render it an island. Media outlets in Saudi Arabia hinted at the possibility of the Saudi government dedicating portions of the canal towards a military installation and a dump site for nuclear waste.
The border was reopened on 4 January 2021. A demarcation process concluded in November 2021, which saw the southern coast of the
Khor Al Adaid confirmed as lying within Qatar's borders.
