Perdue name-dropped several commodities that could see boosted sales to China under the new Trump-Xi trade truce — but the USDA chief also made clear that many details are still up in the air.

Reopening the soybean spigot? Perdue said soybean growers could resume sales to China, the biggest foreign buyer of U.S. soy, as soon as Jan. 1. He said the short-term truce Trump and Chinese President Xi Jinping struck at the G20 meeting in Argentina also opens the door to greater sales of wheat, poultry, beef, pork, rice and sorghum to China, your host and Sarah report.

But, but, but: While China has promised to buy more U.S. ag products (at least according to the White House's readout of the agreement), there's no mention of ending Beijing's retaliatory duties on American farm goods. And Perdue said the potential purchases are "without quantification" yet — so there's no guarantee the truce will be a major breakthrough for soybean exporters.

— "I think everyone is waiting to see exactly what was said and flesh out the details of that very important, promising announcement," Perdue said in Chicago.

Kudlow told reporters on a conference call that he expects Beijing to "quickly" roll back retaliatory tariffs on U.S. ag products and to begin ramping up ag purchases "immediately," Pro Trade's Megan Cassella and Caitlin Oprysko report.

Soy's perspective: John Heisdorffer, president of the American Soybean Association, said the truce was "the first positive news we've seen after months of downturned prices and halted shipments."

— Heisdorffer hopes China will "reopen its market to significant U.S. soybean imports" during the 90-day negotiating period, while a longer-term deal would be "extremely positive."
