Answer:
The biggest impact that Saudi Arabia has had over the years is the supply of oil and its contribution in OPEC. Saudi Arabia has around 20% of the World's proven reserves, and extraction costs are relatively inexpensive. Between the mid-1970s and 2002 Saudi Arabia expended over $70 billion in "overseas development aid."
Saudi Arabia has the most oil of any place in the world. Saudi Arabia is also famous for the religion Islam and is home to Islam's holiest shrines in Mecca and Medina. The King of Saudi Arabia is called the Custodian of the Two Holy Mosques.
