South Korean President Lee Jae-myung will visit the US this month for his first meeting with US President Donald Trump since taking office in June, a high-stakes trip set to spotlight a recently inked trade deal between the allies as well as security issues they share.

Lee will travel to Washington for a summit with Trump on Aug 25 that will also include a lunch between the leaders, South Korea’s presidential office said on Tuesday. The leaders will discuss ways to develop their alliance in a “future-oriented, comprehensive” manner, Lee’s spokesperson Kang Yu-jung said.

“The two leaders are expected to discuss ways to further strengthen their economic cooperation in areas including chips, battery and shipbuilding based on the recently concluded tariff negotiations,” Kang said.  

The three-day trip that will start on Aug 24 takes place less than a month after the two countries reached an agreement on July 31 that allowed South Korea to avoid a threatened 25 percent across-the-board tariff. Under the deal, the US agreed to impose a 15 percent levy on imports from South Korea, including autos, while South Korea pledged to create a $350 billion fund for investments in the US.

The summit will likely feature thorny issues including the future of the US military alliance with South Korea and the details of the investment plan, which remain unclear. A South Korean official earlier said the two countries are discussing expanding Seoul’s defense spending in line with global trends, but the July deal didn’t specify how the US expects Seoul to enhance its security profile.
