Hello. The Trump administration is warning South Korea not to target tech companies with discriminatory regulations and investigations, its latest effort to protect U.S. internet platforms as it threatens higher tariffs on the country.

The move comes after weeks of investigations by South Korean lawmakers and officials into Coupang that could result in regulations, fines and penalties over one of the country’s largest-ever data breaches and other complaints about its business practices.
