The talks are "going well and are nearly complete", VW CEO Herbert Diess told some 500 of the company's top managers from around the world gathered at its headquarters in Wolfsburg.
The possible venture comes as the companies compete for investment and engineering talent with peers as well as technology companies.
The partnership also comes as Volkswagen, navigating global trade conflicts, views its relationship with Ford as strategically important.
"Today we are de facto a very Chinese-oriented company. For this we need a counterweight in the US," Diess said, according to prepared remarks seen by Reuters.
