(Bloomberg) -- Xpeng Inc.’s boss He Xiaopeng met with Volkswagen AG executives in Germany recently, offering a bullish update on its partnership with Europe’s biggest automaker.

The head of the Chinese EV maker held talks with VW Chief Executive Officer Oliver Blume and China head Ralf Brandstätter at the company’s headquarters in Wolfsburg in late September, the CEO said Thursday on his Weibo account.

“I was extremely awed by VW’s capabilities in product and engineering design as well as large-scale manufacturing, and have full confidence and more visions on a long-term win-win collaboration,” He wrote in a post on the Chinese social media platform.

He’s post comes shortly after the loss-making manufacturer confirmed that its procurement chief had been suspended as part of a corruption probe. Xpeng said the investigation would not disrupt production or business operations, and that it “remains vigilant in identifying and rectifying any instances of corruption promptly.”

In July, Volkswagen said it planned to invest $700 million in Xpeng and jointly develop EVs in China with a new model platform. The deal aims to leverage Volkswagen’s scale and Xpeng’s technology to bolster VW’s standing in the world’s biggest car market and help the Chinese partner cut costs to weather a fierce EV price war.

Volkswagen engineers have been meeting regularly with their Xpeng counterparts to develop the new model platform and work out other details of the partnership, He said.

Officially, the tie-up had foreseen potential cooperation on software and supply chains. He’s post suggests that the pair has made headway on the latter.

“The strategic partnership on supply chain allows us to further reduce costs,” He wrote, adding that Xpeng would “learn from VW on going global.”

Xpeng has exchanged much of its senior executive ranks in recent months, with only two of 12 key managers remaining at their posts, He said last month.

A Volkswagen spokesperson declined to comment.
