South Korea's acting president Han Duck-soo ordered on April 3 an "all-out" response to the United States' higher-than-expected reciprocal tariffs on imports from the country.

China is seeking to coordinate its response to U.S. tariffs with Japan and South Korea, Chinese state media said.

China, Japan and South Korea agreed to jointly respond to U.S. tariffs, a social media account affiliated with Chinese state media said on Monday, an assertion Seoul called "somewhat exaggerated", while Tokyo said there was no such discussion.
