Earlier in the talks the U.S. had pressed South Korea to lift restrictions on imports derived from cattle older than 30 months, but Yeo helped defuse that by showing the Americans a photo of massive protests that occurred years ago over concerns about mad cow disease.

South Korea also agreed to invest $350 billion in the United States in projects selected by Trump and to purchase energy products worth $100 billion.

The agreement comes after other American allies, like Japan, clinched their own deals, partly to moderate President Trump’s tariff threats.
