What is unusual about the boundaries of Oman?

Oman has an unusual geographic feature called the Musandam Peninsula, which is separated from the rest of the country by the United Arab Emirates (UAE). The Musandam Peninsula is located on the northern coast of the Arabian Peninsula, and it is surrounded by the Gulf of Oman on three sides. The UAE occupies a narrow strip of land that connects the Musandam Peninsula to the rest of Oman. This unique geographical feature makes Oman one of the few countries in the world with a non-contiguous territory.
