The top U.S. envoy to Korea on Monday named alliance modernization, economic ties and regional cooperation as her priorities, saying "trust and communication" are key to achieving them. U.S. Ambassador Michelle Park Steel made the remarks in a video posted on the embassy's YouTube channel to mark her 100th day in the post. In the video, Steel said her three priorities are "modernizing our alliance, expanding economic opportunities and working with Korea to address regional challenges." "None of these things can happen without trust and communication," she said. Asked what she would tell a young Korean who wonders why the alliance still matters, she said it matters because the two countries "can trust one another when it matters the most."

She also stressed the need to cooperate in adapting to challenges, such as cyber threats and the security implications of new technologies. "The purpose is to protect our people and give the next generation the security to build their future
