The United States again ranked first in global weapons sales last year, signing deals for about $40 billion, or half of all agreements in the worldwide arms bazaar, and far ahead of France, the No. 2 weapons dealer with $15 billion in sales, according to a new congressional study. Developing nations continued to be the largest buyers of arms in 2015, with Qatar signing deals for more than $17 billion in weapons last year, followed by Egypt, which agreed to buy almost $12 billion in arms, and Saudi Arabia, with over $8 billion in weapons purchases. The United States and France increased their overseas weapons sales in 2015, as purchases of American weapons grew by around $4 billion and France's deals increased by well over $9 billion. The report, Conventional Arms Transfers to Developing Nations, 2008-2015," was prepared by the nonpartisan Congressional Research Service, a division of the Library of Congress, and delivered to legislators last week. The annual review is considered the most comprehensive assessment of global arms sales available in an unclassified form. Russia, another dominant power in the global arms market, saw a modest decline in orders for its weapons, dropping to $11.1 billion in sales from the $11.2 billion total in 2014. China reached $6 billion in weapons sales, up from its 2014 total of over $3 billion. The largest buyers of weapons in the developing world in 2015 were Qatar, Egypt, Saudi Arabia, South Korea, Pakistan, Israel, the United Arab Emirates and Iraq.
