North Korean leader Kim Jong-un has reportedly visited an auto factory in South Pyongan Province. 
 
The North's state media Korean Central News Agency(KCNA) said on Tuesday that Kim inspected the factory. The report did not mention Chinese special envoy Song Tao's trip to the North. Kim appears to have made the inspection on Monday.
 
The KCNA on Monday briefly reported that Song returned home and did not mention whether or not he met with Kim during his four-day visit.
 
China's official Xinhua News Agency has also not yet reported whether the special envoy met with Kim, simply saying that Song held talks with the leader of the North's ruling Workers' Party during his trip.
