Riyadh: Saudi Arabia, officially known as the Kingdom of Saudi Arabia (KSA), is an Arab state in Western Asia constituting the bulk of the Arabian Peninsula.
With a land area of approximately 2,150,000 km2 (830,000 sq mi), the gulf kingdom is geographically the fifth-largest state in Asia and second-largest state in the Arab world after Algeria.
Saudi Arabia is bordered by Jordan and Iraq to the north, Kuwait to the northeast, Qatar, Bahrain, and the United Arab Emirates to the east, Oman to the southeast, and Yemen to the south.
It is separated from occupied Palestine and Egypt by the Gulf of Aqaba.
It is the only nation with both a Red Sea coast and a Arabian Gulf coast, and most of its terrain consists of arid inhospitable desert or barren landforms.
Oil was discovered in 1938 and followed up by several other discoveries in the Eastern Province.
Saudi Arabia has since become the world's largest oil producer and exporter, controlling the world's second largest oil reserves, and the sixth largest gas reserves.
The kingdom is categorised as a World Bank high-income economy with a high Human Development Index, and is the only Arab country to be part of the G-20 major economies.
