General Motors Corp’s vehicle sales in China fell in August and September, marking a rare consecutive monthly decline, the Wall Street Journal reported. The announcement came from the automaker’s Asia Pacific President Nick Reilly, who declined to provide any figures for the drop in sales. General Motors has yet to release its third-quarter earnings. "We remain optimistic about growth here. We do expect vehicle sales in China to pick up in the fourth quarter of the year and to continue to outpace global growth as a whole," Reilly was quoted as saying. Consulting firm J.D. Power predicts General Motors will see its China sales contract as much as 5.5% this year, marking its first decline since 1999.
