Pakistan has imported a few light aircraft from a manufacturer in northeast China's Heilongjiang Province to meet its domestic needs, officials said. The 19-seat Y12 series planes are twin-engine, general-purpose monoplanes designed and developed by the Harbin Aviation Industry (Group) Ltd. (HAI), based in China's Heilongjiang provincial capital Harbin. The aircraft are being mainly used for troop transport and emergency rescue operations. By the end of 2005, HAI had sold more than 100 such aircraft to 20 countries and regions, such as Pakistan, Nepal, Peru, Zambia, Tanzania and Namibia.
