Considering how relationships between China and Vietnam were frayed for several years before the war one has to wonder how many industrial facilities were relocated to other parts of the country due to strategic concerns. Vietnam is by no means a blind to it.I know they did. But not so close to the Chinese border because they didn't want a repeat of the Korean war.
A lot of the heavy industry Vietnam built was close to the border area and they all got demolished when the PLA left.
