China has imposed tariffs on American goods and restricted exports from 15 American entities, in response to President Trump's increased tariff on Chinese goods from 10% to 20%. The tariffs will affect imports of chicken, wheat, corn, cotton, soybeans, sorghum, pork, beef, fruits, vegetables, dairy products, and aquatic products from the US, and will come into effect on March 10. This could mark the beginning of a trade war between the world's largest economies.
