WASHINGTON, D.C. (WNAX) – The relationship between the U.S. and China is becoming more tense. That follows the closure of the Chinese consulate in Houston after allegations of spying.

South Dakota Senator John Thune says the gap seems to be getting wider.

Thune says they have had a number of briefings on Chinese activities.

China has been a major buyer of U.S. ag products. Thune says that has to be a consideration as tensions rise.

Thune says the U.S. also has to be careful in using any technology imported from China.
