China sales at General Motors and its two joint ventures shrank 35 percent to some 484,000 in the second quarter from a year earlier, reflecting a two-month lockdown of Shanghai and other government measures to curb a resurging coronavirus outbreak. 

Shanghai and other parts of the country imposed strict travel restrictions and testing rules for much of the spring, stifling economic activity, disrupting vehicle output and shipments and curbing showroom traffic.

Each of GM’s brands posted double-digit declines during the April-June period, according to results released by the U.S. automaker’s China unit. 

GM produces and markets Cadillac, Buick and Chevrolet cars and trucks at SAIC-GM, a passenger vehicle partnership with SAIC Motor Corp. 

It also builds and distributes minibuses under the Wuling brand and entry-level cars for the Baojun marque at a joint venture with SAIC and Wuling Automobile Industry Co.

Cadillac’s second-quarter sales plunged 42 percent to around 37,000. Buick deliveries skidded 43 percent to some 128,000 while Chevrolet sales slipped 37 percent to roughly 40,000.

Wuling deliveries dropped 23 percent to some 268,000 while Baojun’s volume tumbled 79 percent to about 11,000, GM reported.

GM’s China sales have slipped for two straight quarters this year. In the first quarter, the volume fell 22 percent year on year to around 610,000.

For the first six months, GM and its partnerships delivered approximately 1.1 million vehicles in China, a 28-percent drop from a year earlier, according to data released by GM China.
