Fourthly, the tariff measures lead to barriers to US exports to China. The 2019 State Export Report, published by the US-China Business Council on May 1, 2019, stated that in the ten years from 2009 to 2018, US exports to China supported over 1.1 million jobs. The Chinese market continues its importance to US economic growth. Forty-eight states of the US have increased their goods exports to China during the last decade – 44 of them by double digits – while in 2018, when economic and trade friction worsened, only 16 states increased their goods exports to China. Thirty-four states exported fewer goods to China, with 24 of them seeing a double-digit decrease. The Midwestern agricultural states were hit particularly hard. Under tariff measures, exports of American agricultural produce to China decreased by 33.1 percent year-on-year, including a 50 percent drop in soybeans. US businesses are worried that they might lose the Chinese market, which they have been cultivating for nearly 40 years.
