Yemen has a coast.
Yemen ( [ ˈjɛmən ] اليَمَن ) , officially known as the Republic of Yemen , is an Arab country in Western Asia , occupying South Arabia , the southern end of the Arabian Peninsula . The coastline stretches for about 2,000 km ( 1,200 mi ) . It is bordered by Saudi Arabia to the north , the Red Sea to the west , the Gulf of Aden and Arabian Sea to the south , and Oman to the east-northeast . Because of this , Yemen 's capital has been temporarily relocated to the port city of Aden , on the southern coast . Yemen 's territory includes more than 200 islands ; the largest of these is Socotra .
