Perhaps.  A bigger question would be what was its payload and was it deployed?  A rocket is just the delivery mechanism. And, it appears to have deposited something in that orbit, leaving the rocket to fall out after. That's normal, and probably anticipated.  They are always "out of control" at that time.  UPDATE:  https://www.popularmechanics.com/space/a32451633/china-long-march-5b-rocket-debris/  Initial reports suggested the almost 20-ton rocket stage had fallen into the Atlantic Ocean, off the west coast of Africa. But new reports from social media and some African news organizations suggest pieces of the rocket may have been strewn across parts of Cote d'Ivoire. The heavy-lift rocket, which was carrying China's prototype crew capsule, successfully launched from Wenchang launch center on Hainan Island off the country's southern coast.
