WASHINGTON, Sept 26 A top Obama administration official will travel to Beijing at the end of September to discuss ways to improve opportunities for U.S. businesses in China, the Treasury Department said on Wednesday.
Treasury undersecretary Lael Brainard's meetings with Chinese economic officials Sept. 26 and 27 come in the middle of the U.S. presidential campaign in which President Barack Obama's economic policies have dominated the debate.
Obama's Republican challenger Mitt Romney has accused the administration of being soft on China and has vowed to declare Beijing a currency manipulator should he win the presidency in November.
Brainard is visiting China before the Treasury Department is due to release a semi-annual currency report that examines the foreign exchange practices of major U.S. trading partners.
The report, which by law is required to be released Oct. 15 and April 15, is often delayed. The last time China was labeled a currency manipulator was in 1994.
TOKYO, March 29 Shorter-dated Japanese government bond prices slipped on Wednesday as the market took cues from an overnight retreat by U.S. Treasuries, while the longer-dated maturities gained on month-end investor demand.
