Which country did Liaoning ship buy from?

It is Ukraine. The aircraft carrier Liaoning was formerly the USS Varyag, a marshal-class aircraft carrier of Soviet Navy Kuznetsov. When the Soviet Union disintegrated, the carrier Varyag was about 70% completed. However, since the disintegration of the Soviet Union, the carrier Varyag has been lying in the Black Sea Shipyard in nikolayev, Ukraine (the shipyard was owned by Ukraine after the disintegration of the Soviet Union), which has become an unfinished project. The Ukrainian government was bought by Hong Kong businessmen at auction on 1999 and dragged back to China after many twists and turns.
