President Lee Jae Myung held a phone conversation with U.S. President Donald Trump, Sunday, during which Trump shared the outcome of his high-stakes summit last week with Chinese President Xi Jinping.

Cheong Wa Dae said the call was arranged at the request of the Korean side, following the summit in Beijing from Thursday to Friday.

During the 30-minute talk, Trump shared the summit results with Lee as an ally, according to the presidential office.

The two leaders also exchanged views on peace and stability on the Korean Peninsula, reaffirming the importance of continued cooperation and dialogue.

Lee positively assessed the constructive discussions between Trump and Xi on issues concerning the peninsula, while Trump said that, based on close coordination with Lee, he would play the role necessary for peace and stability on the peninsula, Cheong Wa Dae explained.

The two sides agreed on the need to ensure the smooth implementation of the joint fact sheet (JFS), which outlines a set of agreements on trade and security reached during their summit held in Gyeongju, North Gyeongsang Province, in October 2025 on the sidelines of the APEC summit.

The two leaders recalled that the JFS was "a historic agreement that upgraded the Korea-U.S. alliance to a new level," and agreed to make efforts to implement the agreements faithfully.

The topics addressed in the Trump-Xi meeting drew close attention among Seoul officials, as they included tensions over Taiwan and the Strait of Hormuz, all of which have significant implications for Korea’s security, economy and energy supply.

Regarding Taiwan, the U.S. has been urging allies take a more active role in containing China. With its long-standing “One China” policy, Xi warned Trump that issues on Taiwan could lead to a clash if handled poorly.

Concerning the Strait of Hormuz, Korea has been under the U.S. pressure to join its initiatives for restoring freedom of navigation in one of the world’s most crucial energy chokepoints.

The strait handles roughly 70 percent of Korea’s imported crude oil. Currently, 26 commercial ships are stranded in the area as a result of the U.S. war on Iran since Feb. 28 and Tehran’s blockade of the waterway.

The ships include the HMM Namu, a bulk carrier that sustained damage on May 4 from unidentified airborne objects presumed to be launched by Iran.

Washington and Beijing also said after the summit that the leaders discussed issues on Pyongyang and tariffs.

Trump already had a phone conversation with Japanese Prime Minister Sanae Takaichi, Friday, before heading back to Washington after the summit, to share the outcome of his Beijing visit.
