National Development and Reform Commission Vice Chairman Zhu Zhixin said the record trade surplus in 2005 doesn’t warrant an appreciation of the yuan, the Wall Street Journal reported. China’s trade surplus more than tripled in 2005 to US$101.88 billion from US$31.98 billion in 2004, following a 28.4% rise in exports and 17.6% in imports, said state media. "China should follow its own pace" in reforming its foreign-exchange mechanism, rather than bowing to pressure from outside, said Zhu.
