This week we have been talking about the shift in global power and the ascendancy of china. There is no getting away from this fact – China will eventually overtake the U.S. as the largest economy – and both sides have to live with each other.

Nowhere can that be seen more clearly than the one trillion dollars in u-s government debt owned by the chinese.  The U.S. has needed the chinese to fund its overspending and trade imbalance. The Chinese can't afford for the debt to become tainted by reckless U.S. deficits.   The two countries are stuck with each other – and that will become ever clearer in the years ahead.  They are called the G2 – for one reason.  Who needs Hu? They need each other.  This week's Q&A will tackle the speed of China's ascent: Can they overtake the U.S. by as early as 2020?
