North Korea said that it will temporarily close an important sea route between Dalian, China and its west coast port city of Nampho, according to a new UNICEF COVID-19 report published on Wednesday. The move could significantly North Korea's access to humanitarian aid deliveries.

The North Korean government allegedly alerted the U.N. of its decision to temporarily close the route late last month, the report stated. However, it's still unclear why North Korea wants to seal the route and whether or not they've already done it.
