History After 1949 the PLAN negotiated with Britain through Hong Kong to buy some second-hand ships and boats but unable to do so due to the Korean War. As a result, the PLAN turned to the Soviet Union to buy four worn-out destroyers. The purchase was made on 4 June 1953, with prices equivalent to 17 tons of gold each at the time. The Anshan-class ships were withdrawn from active service by the 1990s, but retained three ships as training ship (Taiyuan) and museum ships (Anshan and Changchun). The PLAN retains ownership of the ships through PLAN funded institutions. Ships in class References Notes Bibliography Destroyer classes China–Soviet Union relations
