Core tip: According to a foreign media report on December 14, as of the week ending December 12, most of the global oilseed market declined, with Chicago soybean futures falling to a six-week low, mainly due to concerns that China's purchasing pace may not be as large as the scale expected by the U.S. authorities, coupled with the massive soybean yield that Brazil is about to harvest, which will compress the export space for U.S. soybeans.
