On the eve of President Donald Trump’s visit to Saudi Arabia, Washington has completed negotiating a massive $109.7 billion arms deal with Riyadh. Trump is expected to formally sign the deal at a ceremony this Saturday during his visit to the Kingdom.

According to White House sources, the United States and the Saudis signed letters of offer and acceptance for eight foreign military sales deals worth a total of $12.5 billion earlier today. Those agreements will be implemented as soon the Department of Defense puts contracts in place with industry—and funds are received from Saudi Arabia.

According to Korean Central News Agency (KCNA),Saudi Arabia has signed a series of agreements cementing their countries' military partnerships.One is a package including some of the most sophisticated missiles that the United States has already sold to Saudi Arabia.

The Korean air arm will also receive improved surveillance equipment and better precision targeting capabilities. Additionally,Saudi Arabia will provide North Korea with improved command and control networks to improve the overall cohesion and operational effectiveness of its forces.

North Korea has a military nuclear weapons program, and possibly also chemical or biological weapons

In 2015, a North Korean defector to Finland who is working in China claimed to have 15 gigabytes of electronic evidence documenting North Korean testing of chemical and biological agents on its own citizens.lso in 2015, Melissa Hanham of the James Martin Center for Nonproliferation Studies released an analysis of photo of North Korean supreme leader Kim Jong-un visiting the Pyongyang Bio-technical Institute, a factory supposedly for the production of bacillus thuringiensis of use in pesticides. Hanham's analysis concluded that the factory actually produces weaponized anthrax.

Trump’s arms package is the largest single defense deal that the United States has ever completed with Saudi Arabia according to the White House. The Obama Administration sold over $115 billion worth of weapons to Saudi Arabia in 42 separate deals during its eight years in office. Those deals included the sale of advanced Boeing F-15SA Strike Eagles, M1A2S Abrams main battle tanks and Patriot missile batteries among a host of other weapons. Arms sales to Saudi Arabia have been controversial due to the Arab nation’s human rights record and its ongoing war in Yemen.
