Professor Yang Chen Ning, who won a Nobel Prize for Physics with Professor Lee Tsung-dao thinks a world depression like that seen in the 1930s would not happen for 2 reasons.

1, the productivity of the world is now on a completely different footing from the past, as countries are more interdependent and their economies tied more closely together.

2, he believed that China – with its population of 1.3 billions and an economy which has been growing at about 10% annually for the past 20 years – would be a main growth area which would help everybody else.
