China said on Wednesday that the U.S. has undermined bilateral counter-narcotics cooperation by imposing tariffs on Chinese goods over fentanyl, calling on Washington to stop using the issue as a bargaining chip to "blackmail" the country.

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.

Here are the products subject to China's retaliatory tariffs, and how U.S. farmers are reacting to Trump's trade policy.
