China has already imposed counter tariffs on some import products from the United States immediately after new U.S. tariffs took effect at 12 pm Friday, the country's customs authority said.
In response to the U.S. announcement to impose additional duties on Chinese imports, the Customs Tariff Commission of the State Council announced it would levy additional tariffs for 545 items worth about $34 billion, including agricultural products, vehicles and aquatic products, starting July 6, 2018.
