In August, the American Farm Bureau Federation and other ag and business groups signed a letter that the US-China Business Council letter sent to Tai and Treasury Secretary Janet Yellen, asking them to take “swift action to address the costly and burdensome tariffs and retaliatory tariffs” as well as make sure that Trump's “phase one” trade deal with China is fully implemented. China committed to purchasing $80 billion worth of US ag commodities in 2020 and 2021.
