GM suspended production at its plant in St. Petersburg until 31 August while Ford halted output in Vsevolozhsk, in the Leningrad region until 9 July.

Both carmakers cited unfavourable market conditions, falling demand for cars, and a decline in Russian citizens' purchasing power as reasons for the suspension.

Meanwhile, the country's largest truck manufacturer Kamaz has partially resumed production following a one-week suspension, Oleg Afanasyev, director of the company's department for information policy, told Itar-Tass on Wednesday.

Kamaz has resumed production of iron, steel, and non-ferrous castings, Afanasyev said, adding that the company planned to resume some operations at its machining facilities by the end of the week.
