History Of UAV in Foreign Countries

Modern warfare is the basic driving force for the development of UAVs. The world's first unmanned aerial vehicle (UAV) was built in 1917, but it was used for battlefield reconnaissance during the Vietnam War. Subsequently, in the Middle East War, Gulf War, Kosovo War, Afghanistan war, Iraq War (the second Gulf War) and other local wars, UAV appeared frequently and made many achievements. Especially in Afghanistan, drones have become a worthy protagonist, carrying out several successful "decapitation" operations.
American drones lead the world. The United States first began to develop unmanned target aircraft in 1939, and has developed "Firebee" series and "Chukar" series of target aircraft. Since the 1950s and 1960s, the United States has successfully developed tactical or strategic unmanned reconnaissance aircraft such as "Firebee", "Pioneer", "Hunter", "Predator" and "Global Hawk", as well as the "Predator" improved unmanned reconnaissance combat aircraft, successively in the Vietnam War, the Gulf War, Kosovo War and this military operation in Afghanistan.
Arms export
On February 18, 2015, the Huffington Post published "Toys R Us Opens!" "Headlined with a photo of a Predator attack drone, a news story about the United States opening its doors to selling armed drones to its Allies. It is reported that on February 18, 2015, the US Department of State announced new regulations on the sale of armed UAVs to its Allies, including the specific approval procedures, time and way of the sale of UAVs. This is the first time that the US has given a "green light" to the export of attack UAVs. It is expected that the first sale of the US attack UAVs is the MQ-9 "Reaper" type, which will be sold to the UK. 
Japan has already bought RQ-4 Global Hawk surveillance drones from the United States, and may also seek attack drones in the future. Chinese drones are rapidly gaining ground in Asian, African and Latin American countries, according to military analysts Guancha.cn. 
After the United States opens the "Pandora's box", there will naturally be a lot of unexpected buyers, such as Taiwan, Japan, the Philippines and even India, Vietnam may appear in the ranks of buying American attack drones, such a huge business market, I am afraid that the American industry is unable to keep the "bottom line". It can't be too far for US sold attack drones to appear near China.
