The presidential office said Thursday it is awaiting a response from Washington after proposing a revised plan for managing a $350 billion investment fund. Presidential spokesperson Kang Yu-jung confirmed during a briefing that the revised proposal for the memorandum of understanding had been sent to the U.S. government. Her comments followed an earlier interview in which Kim Yong-beom, the presidential chief of staff for policy, first mentioned the submission of the revised plan to local media. Kang said, adding that Seoul has "various scenarios in mind" and is working to "devise a plan to benefit both countries." In a trade deal signed in July, Seoul pledged to invest $350 billion in the United States.
