 From VOA Learning English, this is the technology report in special English. China recently said it considered launching a drone strike against a Burmese drug trafficker. Naocam was wanted in the killings of 13 Chinese sailors on the Mekong River in 2011. China's top drug official said the plan was to bomb the drug dealer's mountain hiding place in Northeastern Burma using unmanned aircraft. The official said the drone strike idea was passed over in order to capture Naocam alive. He was seized last April in a joint operation with Laos. That China considered using a drone strike is a sign of its increasing development of unmanned flight technology. It also suggests that China is seriously considering using drone attacks outside of its borders. Peter Dutton is with the United States Naval War College. He says China is moving away from its earlier policy of non-interference in international affairs. He says the country is becoming more active in protecting its interests beyond its borders. The United States has led the world in drone technology for years. It is known to use UAV or unmanned aerial vehicle strikes against foreign targets. In recent years China has greatly improved its UAV technology. It showed off many of its new models at a recent air show in the country. One of the drones has a range of over 3,200 kilometers. China is also modernizing its global navigation system to compete with those of the United States, Russia and Europe. The United States exports unmanned aircraft to only a few of its closest allies. China is now seen as an increasingly reliable lower cost supplier. Several countries have bought or built their own UAVs mostly for surveillance purposes. For VOA Learning English, I'm Laurel Bowman.
