China’s Passenger Car Association warned that Elon Musk’s foray into politics risks hurting Tesla Inc.’s already plunging electric vehicle sales.

While the association doesn’t analyze international politics, Tesla is being viewed by some people as political and that’s impacting the company in the short term, Secretary General Cui Dongshu, said during a briefing on Monday.

“As a successful businessman, one should be embracing 100% of the market: treat everyone nicely, and everyone will be nice in return,” he said. “But if you look at it in terms of voting, then half of voters will be friendly to you and half of them won’t be.”

“This is the unavoidable risk that’s come after he got his personal glory,” Cui said, referring to Musk.

Tesla’s share price surged in the weeks after Donald Trump won the US presidential election, betting that Musk’s relationship with the new administration would pay off for the automaker. But the stock just capped a record seventh straight weekly loss as investors renew their focus on the EV makers’ sales, which had already been losing momentum amid an industrywide slump and are now tumbling in key global markets.

In Germany, Tesla’s sales fell 71% in the first two months of this year as Musk endorsed the far-right Alternative for Germany party in the lead up to the election. Deliveries in France slumped 44% in the same period.

Meanwhile, Tesla’s shipments in China plunged 49% in February. Cui attributed the decline to a slow period during which the Model Y is being upgraded.

Overall auto sales in China market rose 26% in February from a year earlier after a vehicle trade-in subsidy was renewed and the Lunar New Year holiday fell partly in January, the association said. Deliveries of EVs and hybrids grew 80%, it said.
