The cultural relics date from the Spring and Autumn Period (770-476 BC) to the Qing Dynasty (1644-1911), encompassing a variety of items, mainly ceramics. They are from provinces including Jiangxi, Anhui, Fujian, Henan, Shaanxi, Hebei and Guizhou.
Their return brings an end to a quarter-century of China's efforts to retrieve lost cultural relics from overseas, said Guan Qiang, deputy director of the administration.
British police seized all the items in an operation that March. They were later identified by NCHA personnel as lost cultural relics of China.Soon, the State Council, China's Cabinet, set up a special cross-departmental working group to bring them home.
In 1998, over 3,000 relics were returned to China after cooperation by law enforcement units, a lawsuit and negotiations.
However, a local buyer of dozens of remaining relics refused to take part in negotiations, and the civil dispute dragged on after hitting a deadlock. The 68 relics remained impounded by British police.
In January, the Metropolitan Police informed the Chinese embassy that the deadline for prosecution in the case had passed, but the whereabouts of the buyer were unknown. The police showed a willingness to return the items to China.
The Metropolitan Police Service handed the artifacts to the Chinese embassy in October.
The relics were transported in tailor-made cases and landed intact in Beijing on Oct 20.
