BEIJING - The world economy has good chances of avoiding a double dip recession and the Chinese economy could expand by about 10 percent this year, said Klaus Schwab, founder and executive chairman of the World Economic Forum.

"I'm not one of those who feel the world will have a double dip," he said ahead of the Summer Davos Forum meeting, which opens on Monday in Tianjin municipality. "I'm fairly optimistic. I think we have learned from the crisis."

Also, yuan appreciation would not help narrow the trade deficit of China's major trading partners, such as the United States, he told China Daily on Friday.
