Car sales in China retreated in June following a rare increase the previous month, signaling the world’s biggest auto market is facing a bumpy recovery from a two-year slump worsened by the coronavirus pandemic. Retail sales of sedans, SUVs, minivans and multipurpose vehicles declined 6.5% to 1.68 million units in June from a year earlier, the China Passenger Car Association said Wednesday. Sales had risen 1.9% in May, the first increase in a year.

Last month, the industry faced a particularly tough year-earlier comparison: Sales jumped in June 2019 as dealers offered discounts to push models that risked becoming redundant by new emission standards taking effect the following month.

Premium marques such as BMW and Mercedes-Benz have emerged from the slump quicker, helped by demand from wealthier consumers, while cheaper local brands have been hit. In the mid-tier of the market, performance has varied: Nissan Motor Co.’s sales rose 4.5% last month in China while Honda Motor Co.’s fell by 4.1%. China’s Geely Automobile Holdings Ltd. had a 21% sales surge.

The industry’s full-year sales may fall about 10% following big declines at the height of the virus crisis early in 2020, PCA Secretary General Cui Dongshu said in April. That would be a third straight annual drop. Sales of new-energy vehicles, including electric cars, also continued to decline, PCA said. NEV sales fell 35% to 85,600 units, following a drop of 26% in May, 30% in April and 49% in March.
