Nobel Prize-winning economist believes in future of China

The economist also expressed confidence in the future of Asia, saying that this region is full of entrepreneur spirit, perfectly capable of adopting modern technology and there is a lot of people here who have those capacities.

"So in the long run, this region will be enormously thriving and will be the center of the world economically and in other respects," said Krugman.

Krugman further mentioned that the US Federal Reserve should not raise interest rate this year even though he suspected they would.
