U. S. Treasury Secretary Timothy F. Geithner reveals that he is fully sure that China will permit the value of the yuan to appreciate against the dollar.

"It is in China's interest that they move to let their exchange rate start to gradually reflect market forces," Geithner said in an interview on Bloomberg Television's "Political Capital with Al Hunt," airing this weekend. "I'm confident they're going to do that".

China, the world's fastest-emerging major economy, was witnessed to stagnate its currency's 21 percent, three-year advance against the dollar in July 2008 in a view to assist exporter's weather recessions in the U. S., Europe and Japan.

China has kept the currency at nearly 6.8 to a dollar, a policy that has hampered the competitiveness of Asia's export-dependent nations, whose currencies have marked a rise this year.

In April, China recorded a trade surplus of $1.68 billion as exports marled a rise 30.5 percent from a year ago, the customs bureau reported on May 10.

The People's Bank of China has hinted that it will likely permit the Yuan to rise against the dollar, Xia Bin, one of the bank's academic advisers, was quoted as saying in China Business News newspaper on May 11.
