The yuan hit its highest level against the U.S. dollar since early March yesterday, as the breach of a psychological resistance level sparked follow-through buying, traders said. Spot yuan opened at 6.1208 per dollar, breaking through the 6.1200 barrier in early trade and touching an intraday high of 6.1172. SD-Agencies
