General Motors' car venture in Shanghai said it sold 612,072 vehicles in the first half of the year, up 27.5 percent from a year earlier.

The tally includes 12,067 exported vehicles, Shanghai GM, the Detroit automaker's tie-up with SAIC Motor Corp <600104.SS>, said in a statement on its website late on Monday.

In June, the venture sold 104,472 Buick, Chevrolet and Cadillac vehicles, it said, without providing the year-earlier tally.
