More 'aggressive' investment from General Motors

Automaker pledges to add new models to its range over two years
General Motors will continue "investing aggressively" in the world's biggest auto market, according to the company's top executive.
The biggest foreign automaker in China by sales volume has also promised to bring more than 20 new and upgraded models to the country in the next two years.
"As our largest market, China played a significant role in General Motors' success in 2010. We will continue investing aggressively in the country to ensure the long-term success of our company," said Dan Akerson, the US automaker's chairman on Tuesday in Beijing.
It was the first time Akerson had visited China since stepping into the position on Jan 1 after a stint as chief executive officer since September.
