The United States is finalizing a $300 billion arms deal with Saudi Arabia, according to a White House official.

“We are in the final stages of a series of deals,” Reuters quoted the official as saying on Friday, a week before U.S. President Donald Trump visits the oil-rich kingdom on his first foreign trip.

The official further said that the deals exceed $100 billion at this point and might be increased to $300 billion over a 10-year period.

Washington is aiming to bolster Riyadh’s armed forces while making sure that Israel, America’s main ally in the Middle East, maintains its military edge in the region, according to the unnamed official.

Trump will make a visit to Saudi Arabia before heading to Israel on his maiden international trip, a move that underlines the Arab country’s importance in his foreign policy.

Saudi Arabia and its allies, backed by the U.S. and other Western powers, have been arming militant groups fighting in Syria and Iraq.

The militant groups, among which ISIS emerged and became very powerful, want the Syrian President Bashar al-Assad ousted.

Syrian crisis started in 2011 and so far it has claimed the lives of hundreds of thousands of civilians.
