According to this year's global power rankings, published by US News and World Report, two Arab countries are among the world's most powerful. 

Saudi Arabia ranked 9th most powerful country in the world, followed by the United Arab Emirates at No.10. 

Overall, the United States outranked all other countries as the most powerful in the world, followed by Russia (No. 2) and China (No. 3.) 

Power was a sub-ranking on the 2018 "Best Countries" report, which placed the UAE at No. 23 and Saudi Arabia at No. 37 overall. 

The "Giant of the Middle East"

US News describes Saudi Arabia as the "giant of the Middle East." 

The country is home to the holy city of Mecca, where millions of Muslims come together to perform annual pilgrimage otherwise known as hajj. 

The country's oil reserves have made it one of the most significant players in the world. The kingdom makes up around 18 percent of the world's petroleum reserves, according to OPEC. 

It is the 2nd largest OPEC Member Country. 

However, in recent years, low oil prices have taken a toll on the Saudi economy. 

Thus, the kingdom has steered away from its dependence on oil with wide-reaching economic reforms, including instituting austerity measures and implementing taxes.
