The dollar recovered slightly in Asian trading Wednesday against the Japanese yen from overnight levels in New York on technical buying, although bullish sentiments on the dollar appeared to be fading. The U.S. dollar was trading at 106.88 yen by midafternoon in Tokyo above the 106.75 yen it bought in New York later that day. The euro rose to US$1.3073 Wednesday afternoon from US$1.3028 late Tuesday and to 139.71 yen from 139.55 yen. The dollar was mixed against other regional currencies, edging up to 1.6487 Singapore dollar from 1.6478 the previous day, but falling to 1,009.2 South Korean won from 1010.5 Also weighing on the dollar against the yen was U.S. Treasury Secretary John Snow's comments overnight, prodding China to adopt a more flexible exchange rate system. Snow made similar comments at a recent meeting of finance officials of the Group of Seven leading industrial nations. The Chinese currency is now pegged to the dollar and letting it trade more freely is believed to push the yuan higher, bringing other Asian currencies higher with it.
