President Lee Jae Myung begins a visit to Washington on 23 August with fifteen senior executives from South Korea’s largest companies. The trip comes ahead of his 25 August summit with President Trump and will address trade, investment pledges, energy purchases and defence cost-sharing between the two countries.

President Lee Jae Myung of South Korea will travel to the United States beginning 23 August in the company of fifteen senior business executives from the country’s largest conglomerates. The trip precedes his summit with President Donald Trump on 25 August in Washington. Lee’s delegation includes leaders from Samsung, SK, Hyundai and LG among others. They will form the economic component of the visit while the summit is expected to focus on alliance and economic security matters. The trade backdrop is the agreement concluded in July under which the United States will impose a 15 per cent tariff on South Korean imports instead of the previously proposed 25 per cent. South Korea pledged a $350 billion investment in the United States as part of a broad economic package. On 19 August Lee met the heads of major firms to coordinate investment plans and economic strategies ahead of the summit. Their cooperation spans semiconductors, automobiles, shipbuilding and other critical industries. The United States may also expect further investment announcements beyond existing projects. The two sides are set to explore partnership in manufacturing and economic security sectors. The summit follows months of trade tensions that involved significant tariff threats and emergency measures on both sides. The new agreement marks a de-escalation in the economic dispute. South Korea has also committed to purchase $100 billion in US energy products. Arrangements for this component may be refined during the meeting. Defence questions are also on the agenda. South Korea currently spends around 2.3 to 3.5 per cent of GDP on defence while the United States has pushed for up to 5 per cent. There will be discussions over the cost of maintaining US troops on the peninsula. The wider strategic context includes modernising the alliance amid rising threats from North Korea and evolving regional security dynamics. US interest in a shift in alliance posture may reframe aspects of troop deployment and joint deterrence. Industrial cooperation in areas such as batteries, chips, energy and shipbuilding forms a central pillar of the summit agenda. South Korea may also address access for nuclear fuel reprocessing or enrichment under industrial and environmental prerogatives. This trip marks Lee’s first summit with Trump since assuming office in June. It aligns the presence of leading companies with diplomatic outreach in Washington....
