"They should understand that China is doing its best," Wu said. "China's 
economic restructuring needs a process." 
The senators will meet officials in Beijing on March 21-23, in Shanghai on 
March 23-24, and in Hong Kong on March 25. 
What they learn on the trip will determine whether they proceed with a vote 
on their bill that would apply 27.5 percent tariffs on Chinese imports. A 
semiannual report due April from the Treasury may accuse China of manipulating 
its currency. 
Manipulator? 
"We hope they will not label China as a currency manipulator," said Liu 
Jianchao, a spokesman for China's foreign ministry in Beijing. "We'll tell them 
U.S.-China relations are beneficial to both sides." 
Ma Kai, head of the National Development Reform Commission, China's top 
planning body, on March 17 said there have been two- way movements in the yuan 
so "there has been no manipulation." 
The central bank said on Feb. 21 that it aims to deepen reform of the 
foreign-exchange system as local companies have "adapted" to last year's 
currency changes. 
Shipments abroad helped the Chinese economy double in size in the past 
decade, leapfrogging the U.K. last quarter to become the world's fourth-largest. 
China's trade surplus tripled to a record $102 billion last year. 
Seeks Speculators 
"Previously China had a fixed currency and all speculation was bad," said 
Steven Chang, global markets vice president in Hong Kong at State Street Bank 
& Trust Co., a unit of the world's biggest provider of investment services 
to institutions. "Now they're allowing a lot more volatility and they're wanting 
more traders and speculators on both sides to trade it"' Chang says the yuan may 
advance 3 percent to 5 percent this year. 
China on July 21 ended its peg to the U.S. currency that had been in place 
since 1995 and said it would allow the yuan to fluctuate versus an unspecified 
basket of currencies.
