The Chinese government announced the tariffs last week, shortly after President Trump raised tariffs on Chinese products for the second time since he took office in January. The Chinese tariffs will include a levy of 15 percent on U.S. products like chicken, wheat and corn, as well as 10 percent on products like soybeans, pork, beef and fruit.

China has announced retaliatory tariffs on some Canadian farm and food imports, after Canada imposed duties in October on Chinese-made electric vehicles and steel and aluminum products.

China also imposed import levies covering $21B worth of US agricultural and food products including soybeans, wheat, meat and cotton.
