South Korea's new president, Lee Jae Myung, will face a pivotal moment on Monday when he meets U.S. President Donald Trump in Washington for their first summit, as the countries' decades-old alliance strains to confront rapid geopolitical changes.

Washington

South Korean President Lee Jae-myung is attending his first summit with US President Donald Trump, a meeting that comes just two months after Lee took office following the impeachment of his predecessor. The summit is seen as crucial for reaffirming the US-South Korea security alliance, especially as concerns persist about the possibility of the US reducing its security commitments in the region.

Lee's visit follows his first official trip to Japan, where both countries pledged closer ties and stronger trilateral cooperation with the US in response to China's growing influence and North Korea's ongoing missile threats. The summit agenda is expected to include discussions on sharing the costs of hosting US troops and coordinating responses to North Korea's recent missile tests.

South Korea's Lee faces pivotal test at first summit with Trump

He's barely two months into office after the impeachment of his predecessor. As South Korean President Lee Jae-myung heads to Washington for a summit with Donald Trump, concerns about a US retreat in security commitments loom large, as this analyst explains. One of the essential elements is to try and build a relationship that will ground the security alliance going forwards throughout President Trump's term in office. That is coupled with the fact that under Lee's predecessor, we had immense domestic turmoil within South Korea, and the alliance has been touted as being on somewhat difficult grounds. The summit comes after Lee made his first official visit to Japan last week. Both Seoul and Tokyo rely heavily on the US to counter China's mounting regional influence. They host some 80,000 US troops, but there are fears in South Korea that Trump will demand higher payments to support their presence. In spite of their deep-rooted historical grievances, South Korea and Japan pledged closer ties ahead of Lee's meeting with Trump. In the fast-changing global political landscape, we agreed that unwavering South Korea-Japan and South Korea-US-Japan cooperation is more important than ever and agreed to work towards stronger trilateral cooperation. The two neighbours also vowed to boost coordination against North Korea's nuclear missiles and threats, a topic that Trump and Lee are also expected to discuss. Over the weekend, North Korean leader Kim Jong-un oversaw the test-firing of two new air defence missiles, according to state media. This after Pyongyang accused Seoul of stoking tensions on the border.
