North Korea continued work on a new pier at its primary oil facility in Nampho throughout June and August, satellite imagery from Planet Labs shows, despite lower imports from China during the same period.

Work on a new pier which would give the facility additional capabilities for offloading fuel products or ship refueling, started in the first half of 2016, though seemed to stall before the project was complete.

But more recent imagery indicates the work resumed in the summer months, with photos from September showing the construction nearing completion.
