Agreed, the A-Class may help. Mind, Audi is already far ahead of Mercedes in China, with 405.838 sold in 2012 versus 196.211 and plans an increase to 700.000 by 2015. MB plans around 300.000 there by 2015 according to a presentation in 2011.
MB confirmed 2015 plans.

And will start producing the B-Class in Beijing?
Daimler AG's CEO Zetsche: We'll hike Mercedes sales 50% by '15.
Daimler AG CEO Dieter Zetsche vowed to raise Mercedes-Benz China sales 50 percent to 300,000 units by 2015, part of his campaign to revive stalled sales in the fast-growing market.
At Daimler's annual press conference in Stuttgart, Zetsche said two-thirds of Mercedes vehicles sold in China in 2015 will be produced there too.
Daimler soon will launch an engine plant in Beijing, and will expand Chinese production of its C-class sedan, long-wheelbase E-class sedan, and its GLK crossover. Likewise, Mercedes-Benz will start producing its compact B-class cars in China.
To sell those cars, Mercedes-Benz will add 50 new dealerships each year -- mostly in China's interior cities.
Zetsche announced the turnaround plan after Mercedes-Benz sales in China last year rose only 2 percent to 196,200 units. By contrast, BMW group sales jumped 40 percent to 326,400 units, while segment leader Audi's sales soared 30 percent to 405,800 vehicles.
In December, Daimler merged its Chinese sales operations for imported and locally produced Mercedes cars, and it named Hubertus Troska to the management board with responsibility for China, a new position.
Earlier this month the company announced that it would acquire a 12-percent stake in BAIC Motors Inc., its Chinese joint venture partner, and would gain two seats on that company's board of directors.
"These changes will not have obvious effects overnight, but they will start to make a positive impact over the course of this year," Zetsche said.
