South Korean Ambassador to the United States Kang Kyung-wha said that Seoul is closely monitoring developments related to the possible dialogue between the U.S. and North Korea ahead of U.S. President Donald Trump’s April visit to China, and keeping all possibilities in mind.

At a meeting with South Korean correspondents at the Korean Cultural Center in Washington on Tuesday, Kang said the embassy has been in frequent consultation with the U.S. State Department over North Korea policy.

The top envoy said the U.S. has consistently stated that its policy toward North Korea remains unchanged, and that it will closely coordinate with South Korea before and after the fact to avoid surprises.

Regarding a recent U.S. Supreme Court ruling that struck down reciprocal tariffs, Kang noted the absence of clear guidance on refunds for duties already paid, leaving uncertainty over reimbursement procedures.

She said the government would respond in line with national interests while the embassy would monitor U.S. follow-up measures and work with business groups to ensure accurate communication of any refunds.

On follow-up measures to last year's South Korea-U.S. summits, Kang pledged to facilitate cooperation in uranium enrichment, spent nuclear fuel reprocessing and shipbuilding.
