Is China's growth model sustainable?

Back in 2007, Premier Wen Jiabao called the Chinese economy increasingly unstable, unbalanced, uncoordinated and ultimately unsustainable.

He has used the same language this year and there's every chance the description will still apply in another four years.

The timing of when China's growth model will "ultimately" run out of steam is probably the most critical question facing the world economy.
