YANKTON, S.D. (WNAX) – President Trump announced last week that he would impose a ten percent tariff on up to three hundred billion dollars of Chinese imports starting next month.

That in addition to the twenty five percent tariffs already on two hundred fifty billion dollars in goods.

South Dakota Senator John Thune says the President is continuing his hard line on trade.

Thune says the additional tariffs should hit the Chinese economy.

Thune says US trade negotiators tell them the tariffs are having an impact.

Economists estimate the new round of tariffs could cost US households an average of two hundred dollars a year in higher costs.
