The Detroit-based company initially intends to import between 30,000 and 40,000 Envisions to the US market, where demand for gasoline-guzzling pickups and SUVs has been strong amid low fuel prices, the newspaper said.

The move would add a third SUV to Buick's lineup in the US, joining the Encore, built in South Korea, and the Enclave, built in Michigan.

"GM officials briefed on the plan say importing the Buick Envision would fill a gap in the brand's product line, and isn't a cost-saving measure," another reports stated.

GM shares lost 1.3 percent at USD 35.09 in a sharply lower market.

Buick is one of GM's most popular brands in China, where its sells roughly four times as many as in North America. But car sales are slowing in China, where GM has installed a huge production base over the past decade.

News of Chinese-made GM imports to the US would likely rile the United Auto Workers union, the newspaper said.

The UAW has agreed a tentative four-year labor contract with GM and is pushing members to ratify it. The union reported last Friday that so far 55.4 percent had voted for the agreement and 44.6 percent opposed it.
