Korea's transport ministry said Wednesday it has imposed fines on Vietnam Airlines and Aero Mongolia on charges of violating the country's aviation law. Vietnam's flag carrier was slapped a fine of 25m won ($19,296) for a lengthy wait with passengers aboard. On July 14, the airline's plane, which departed from Hanoi, temporarily landed at Incheon International Airport, west of Seoul, before arriving at Gimhae International Airport in Korea's southeastern port city of Busan. The aircraft stayed in Incheon airport's movement area for more than five hours with passengers aboard while preparing for takeoff. Under the Aviation Business Act, an international aircraft cannot wait in the movement area with passengers aboard for over four hours. The Mongolian flag carrier was imposed a 10m-won fine for operating the Incheon-Ulaanbaatar route since July 1 without approval.<br/>
