What is the length of the border between Saudi Arabia and the UAE?
United Arab Emirates
The United Arab Emirates is situated in Southwest Asia, bordering the Gulf of Oman and the Persian Gulf, between Oman and Saudi Arabia; it is in a strategic location along southern approaches to the Strait of Hormuz, a vital transit point for world crude oil. The UAE lies between 22°30' and 26°10' north latitude and between 51° and 56°25′ east longitude. It shares a 530-kilometer border with Saudi Arabia on the west, south, and southeast, and a 450-kilometer border with Oman on the southeast and northeast. The land border with Qatar in the Khawr al Udayd area is about nineteen kilometers () in the northwest; however, it is a source of ongoing dispute. Following Britain's military departure from UAE in 1971, and its establishment as a new state, the UAE laid claim to islands resulting in disputes with Iran that remain unresolved. UAE also disputes claim on other islands against the neighboring state of Qatar. The largest emirate, Abu Dhabi, accounts for 87% of the UAE's total area (). The smallest emirate, Ajman, encompasses only (see figure). The UAE coast stretches for more than along the southern shore of the Persian Gulf. Most of the coast consists of salt pans that extend far inland. The largest natural harbor is at Dubai, although other ports have been dredged at Abu Dhabi, Sharjah, and elsewhere. Numerous islands are found in the Persian Gulf, and the ownership of some of them has been the subject of international disputes with both Iran and Qatar. The smaller islands, as well as many coral reefs and shifting sandbars, are a menace to navigation. Strong tides and occasional windstorms further complicate ship movements near the shore. The UAE also has a stretch of the Al Bāţinah coast of the Gulf of Oman, although the Musandam Peninsula, the very tip of Arabia by the Strait of Hormuz is an exclave of Oman separated by the UAE. South and west of Abu Dhabi, vast, rolling sand dunes merge into the Rub al-Khali (Empty Quarter) of Saudi Arabia. The desert area of Abu Dhabi includes two important oases with adequate underground water for permanent settlements and cultivation. The extensive Liwa Oasis is in the south near the undefined border with Saudi Arabia. About to the northeast of Liwa is the Al-Buraimi oasis, which extends on both sides of the Abu Dhabi-Oman border. Lake Zakher is a man-made lake near the border with Oman. Prior to withdrawing from the area in 1971, Britain delineated the internal borders among the seven emirates in order to preempt territorial disputes that might hamper formation of the federation. In general, the rulers of the emirates accepted the British intervention, but in the case of boundary disputes between Abu Dhabi and Dubai, and also between Dubai and Sharjah, conflicting claims were not resolved until after the UAE became independent. The most complicated borders were in the Al-Hajar al-Gharbi Mountains, where five of the emirates contested jurisdiction over more than a dozen enclaves.
