China is considering proposals to slash import duty on passenger cars by about half, a move that’s set to give a lift to luxury-auto makers such as BMW AG and Toyota Motor Corp.’s Lexus unit, according to people with direct knowledge of the matter.

The State Council, or China’s cabinet, is weighing plans to reduce the 25 per cent levy -- which has been in place for more than a decade -- to 10 per cent or 15 per cent, said the people, who asked not to be identified as the deliberations are private. An announcement of a decision could be made as early as next month, the people said.

The move comes as investors fret about a mounting trade war between the U.S. and China. While an announcement could be claimed in some quarters as a concession to President Donald Trump, it may ultimately end up benefiting European and Asian carmakers more than their American counterparts because of China’s outstanding threat to slap an additional 25 percent import duty on U.S-made automobiles.

China also argues that its plan to reduce import tariffs on foreign vehicles is long-standing and has rejected previous efforts by Trump to claim credit for it.

Shares of state-backed automaker BAIC Motor Corp., which counts Daimler as a partner, closed 3.6 percent lower in Hong Kong, after sliding as much as 6.4 per cent on the news. Brilliance China Automotive Holdings Ltd. fell 3.2 per cent. On the Frankfurt exchange, Volkswagen climbed 2.1 per cent at 2:24 p.m., while BMW added 1 per cent.

China’s finance ministry didn’t respond to a fax seeking comment.

China is heeding decades-long pleas from foreign carmakers for better access to its auto market, as its own manufacturers prepare to expand abroad. Last week, China announced a timetable to permit foreign automakers to own more than 50 per cent of local ventures.

China imported 1.22 million vehicles last year, or about 4.2 per cent of the country’s total sales of about 28.9 million automobiles. At the Boao Forum this month, President Xi Jinping reiterated China’s commitment to reduce import tariffs on vehicles. In response, Tesla Inc. Chief Executive Officer Elon Musk lauded the move as a "very important action by China.”

High-end autos, in particular, will feel the effects of a tariff cut, as less of their production has moved locally. For example, Lexus would benefit as the only premium Japanese marque that doesn’t manufacture in China or hasn’t announced plans to do so.

Yet Lexus says it’s increasing its focus on China, unveiling a redesign of its popular ES sedan at the Beijing auto show this week. The car has more room in the back seat to cater to affluent young Chinese with families and customers who prefer to be chauffeured.

At the event, Mercedes debuted a long-wheelbase variant of the A-Class compact sedan to cater to Chinese tastes. Rupert Stadler, head of VW’s Audi unit, said a lowered tariff would have “big potential” for the brand, which currently relies on imports for 10 percent of its China sales.
