Sino-North Korean Friendship Bridge Closure

On November 24, 2017, Chinese Foreign Ministry spokesperson Geng Shuang told reporters that the Sino-North Korean Friendship Bridge will be closed temporarily in the “near future” while North Korea undertakes repairs to the road surface on its side of the bridge. Geng did not provide a specific date for how long the bridge would be closed but simply stated that “[i]t will be reopened after the repair is finished” and provided no further details such as the nature of the repairs. 1 While this announcement sounds like a routine report, as the bridge is sometimes closed for maintenance, there is speculation that it is an effort by China to bring pressure on North Korea over its continuing ballistic missile and nuclear weapons development programs.

Built during World War II, the Sino-North Korean Friendship Bridge is a combination rail and road bridge that crosses the Yalu River (Korean: 압록강 Amnok-gang) connecting the Chinese city of Dandong with the North Korean City of Sinuiju. It is a crucial conduit for commerce and reportedly carries approximately 70% of the trade between the two countries.


While not a definitive confirmation of the bridge’s closure, a detailed analysis of DigitalGlobe satellite imagery from November 24th (the day of Geng’s statement) shows no activity on the bridge—repair or otherwise. Additionally, there is minimal presence of trains in either the Dandong or Sinuiju rail stations or railyards, and a number trucks, buses and cars (approximately 90 in Dandong and approximately 40 in Sinuiju) are parked at the customs stations on either side.

There is a minimal presence of trains in the rail station and freight yard.

In contrast to the satellite imagery, however, social media accounts captured first-hand visual movement of truck traffic on the bridge as late as December 3, 2017. 2 Other media outlets reported that the bridge repairs were scheduled to start on November 24th but that the work may have been delayed until mid-December. 3

The observations support the following assessments:  1) that the bridge has not yet been closed to traffic but the imagery captured a time when there was no traffic present on the bridge; or 2) the bridge was closed temporarily around the time of the November announcement and reopened to allow vehicle traffic to continue until the re-scheduled repair date in December. Additional observations will be necessary to determine the presence of actual repair work on the bridge and the impact on bilateral trade activity in the near future.
