China has blocked or halted soy imports from certain brazilian exporters, with some outlets reporting that five brazilian soy exporters have been banned. The move appears to be related to tighter checks and a food safety probe, although the exact nature and scope of the dispute are unclear. Reports also suggest that china may be shifting its soybean imports, with some indicating increased investment in latin america and potential increased purchases from the us, while others suggest us soybean sales to china may be lagging.
