DMZ Summit May Ease Some Tensions, But Underlying Issues Remain Dong Hyuk Lee President Donald Trump made history Sunday by becoming the first sitting U.S. president to set foot on North Korean soil. But the way the summit came about was no less significant. Trump's visit to the demilitarized zone (DMZ) between North and South Korea had been planned for some time with Seoul's assistance. But according to public remarks by Trump and North Korean leader Kim Jong Un, Trump's offer and Kim's acceptance of the meeting both came at a moment's notice. The unexpected summit was a clear demonstration of growing rapprochement between the two leaders. However, it remains unclear whether the warming ties between the two will lead to improved relations between their countries. The future of U.S.-North Korea relations is likely to depend on whether the sides can resolve the nuclear issue diplomatically. Revival of diplomacy Since the failed Hanoi summit in February, Washington and Seoul have been seeking ways to revive diplomacy with North Korea, and many experts saw Trump's visit to South Korea as the last best chance to salvage the process. The two allies appear to have accomplished that mission with North Korea's commitment, according to Trump, to resume talks "over the next two or three weeks."
