North Korea has been undertaking repair and beautification work on the 170-kilometer-long, four-lane Pyongyang-Kaesong Expressway since last week, a development potentially linked to preparations for a U.S.-North Korea summit, according to reports. The highway connects the capital city of Pyongyang to Panmunjom. The extensive work on this crucial route, which has been under traffic control, suggests a focus on infrastructure enhancement. This activity coincides with reports of North Korean Foreign Minister Choi Son-hee's surprise visit to Russia, which some analysts suggest may be an effort to gain understanding or support for potential U.S.-North Korea engagements. While specific details regarding the U.S.-North Korea summit remain unconfirmed, the timing and scale of the expressway repairs indicate a significant national effort. Further information on the nature of these preparations is expected as developments unfold.
