Give me a break on your 2 cents analysis. You speak like you are a pro making these kind of stuffs. A little search on google does not make you a genius as every one can do.
Copy from China? what a fuking joke. Every made in China tech is copied from the world. You China invent shiit. In the article clearly stated the tech already existed in the world. However, his version has more to it, fly higher. He also stated his unmanned space craft is patented with a Singapore company. (The reason I mentioned Singapore in here because if not you Chinese morons will assumed that Viet copy from you and or inferior tech. Similar to that of Bphone you Chinese said copy from China while it is well known you Chinese copy all these kind of stuffs from westerns.)
The guy on the left is Singaporean his partner, he is on the right and his unmanned space craft behind.
Do little bit more research before spill none sense. Chinese is not center of the world. Vietnam is not China, if an invention is copycat, it wont go to headline. Unlike China, every invention come form China sounds like Chinese invented but the fact it is already existed, the worst thing is Chinese article disregard any facts and credit to the Chinese copycat.
