“Infrastructure improvements continue at Yongbyon,” Jenny Town, managing editor of 38 North, said via Twitter on Wednesday.
“Underscores reason why an actual deal is necessary, not just a statement of lofty goals,” she added.
The upgrades are thought to include a new cooling water pump house, a number of new buildings, a completed construction on a cooling water reservoir and a possible radiochemical laboratory.
To be sure, 38 North noted that continued work at the Yongbyon facility should not be seen as having any significant impact to North Korea’s pledge to denuclearize. Instead, the report says the country can be expected to proceed with “business as usual” until specific orders are issued from Pyongyang.
Earlier this month, Kim Jong Un committed to “complete denuclearization” in meetings with Trump and South Korean President Moon Jae In. However, critics of the deal said the agreement lacked specific details of exactly how and when that would happen while offering too much to North Korea in return.
