"Broader market sentiment was dampened by ongoing trade tensions between the U.S. and China," said Joe Manimbo, senior market analyst, at Western Union Business Solutions in Washington.
China has slapped extra tariffs of up to 25 percent on 128 U.S. products including frozen pork, as well as on wine and certain fruits and nuts, in response to U.S. duties on imports of aluminum and steel, China's finance ministry said.
The tariffs, to take effect on Monday, match a list of potential tariffs on up to $3 billion in U.S. goods published by China on March 23.
