In the case of the China-U.S. squabble, Trump imposed aluminum and steel tariffs in early March in order to protect those American industries.
The list of goods affected by the new tariffs includes seafood, fruits and vegetables, grains and tobacco.
"As a result of China's retaliation and failure to change its practices, the president has ordered USTR to begin the process of imposing tariffs of 10 percent on an additional $200 billion of Chinese imports", U.S. Trade Representative Robert Lighthizer said in a statement.
United States tariffs are the first stage in levies threatened by the Trump administration on a total of $450 billion worth of Chinese goods. China responded with levies of its own, targeting $34 billion in US products such as pork and whiskey. The first round of tariffs covered Chinese products ranging from farming plows to machine tools and communications satellites.
The US is now considering levying duties on a further $16 billion in Chinese goods, after a public hearing later this month.
Many others in the US are already feeling the effects of the tariffs.
The International Monetary Fund has warned that a full-blown trade war could undermine the broadest global upswing in years.
"We encourage companies to optimize the structure of imports, increase imports of soybean, agricultural products, as well as seafood and cars from other countries and regions", said the ministry, explaining that the measures are aimed at mitigating the effects of the trade war with the United States.
"The Trump administration is gambling that by wielding such a big club, it will force China to back down", said Edward Alden, a senior fellow at the Council on Foreign Relations.
