Investing.com – U.S. futures were mostly flat on Wednesday as China disappointed hopes of major exemptions from tariffs for U.S. agricultural exporters and President Donald Trump renewed his attack on the Federal Reserve.

China published a list of products that will be exempt from 25% tariffs introduced last year, but did not include soybeans, pork or corn. Products exempted included cancer drugs and lubricant base oil. Tariffs on agricultural imports are among the most contentious issues in the trade dispute between Washington and Beijing, as China is one of the biggest consumers of American soybeans.

President Trump tweeted that the exemptions were evidence that China is “being hit very hard” by the tariffs he has imposed, but drew more attention with a fresh attack on “boneheads” at the Fed, who he said should cut U.S. interest rates to “ZERO, or less”.
