BEIJING, CHINA — U.S. soybean exports to China have fallen to their lowest level since at least 2004 as a trade war continues between the two nations, Bloomberg reported.

China imported 614,806 tons of soybeans from the U.S. in June bringing the total for the first half of the year to 5.9 million tons. Bloomberg said according to its calculations that was the lowest level in 15 years.

Senior U.S. officials are meeting in China on July 29 for the first high-level, face-to-face negotiations since May, the news agency said.

Presidents Donald Trump and Xi Jinping agreed to a truce in late June, and the Chinese government last week is said to have approved five companies to buy some U.S. soybeans free of retaliatory import tariffs.
