Notes

“Which country dominates the global arms trade?” Tim Bowler

May 10, 2018.
BBC News. It is estimated that the US accounts for 34% of all global arms sales, up from 30% five years ago. Total international trade in arms now worth about $100 billion per year. US arms exports are 58% higher than Russia, the world’s second-largest exporter. The Middle East accounts for almost half of US arms exports received during 2013 – 17. China’s arms exports rose by 38% between 2008 – 12 and 2013 – 17. The major exception to the rise in arms sales is Africa, arms imports falling by 22% between 2008 – 12 and 2013 – 17.
