Air China Cargo made four flights from Urumqi to Minsk, Belarus between 8 and 11 January, likely delivering military equipment, reports Belarusian monitoring group Belarusian Hajun. On each of four days, the same Boeing 747 freighter (registration number: B-2476) touched down in Minsk carrying unknown cargo at around 9:30-10:10 a.m. local time and departed roughly three hours later on each trip, which is enough time to unload the military shipment, Hajun suggests.
In contrast to regular cargo flights that make use of Minsk Airport’s logistical facilities, B-2476 consistently parked at the designated spot reserved for aircraft transporting Belarusian officials. Satellite imagery confirms that during its four visits, the Chinese aircraft occupied this exclusive government ramp. This VIP stand is positioned apart from other facilities, enhancing security and enabling the freighter to bypass customs control procedures.
According to Belarusian Hajun, B-2476 delivered military equipment from China to Belarus without undergoing customs clearance. The cargo quickly left the airport to avoid attracting attention, as there was limited space for military cargo parking.
