Private exporters announced the cancellation of close to half a million mt of soybean export volumes to China. However, the news failed to dent the upward momentum seen on soybean futures contracts, which received fresh impetus over the weekend on a lack of rain in Argentina. A total of 455,000 mt of soybean exports were cancelled. Although much of the volume was offset by export sales of 314,000 mt of soybeans to unknown destinations.
