China made its biggest purchase of U.S. sorghum since April last week, according to U.S. Department of Agriculture data issued on Thursday, as Washington and Beijing revive discussions to end their trade war.

The world’s top sorghum importer bought 51,072 metric tons of the grain even though China imposed a 25% tariff on American shipments in July 2018 as part of the tit-for-tat trade dispute. The purchases will likely be used to feed livestock or make a fiery Chinese liquor called baijiu.
