"To give the peace prize to a convicted person in China...this shows no respect for judicial system in China. What a convicted person should be allowed or not allowed to do is up to judicial authority," Chinese Foreign Ministry spokesman Ma Zhaoxu told reporters here.
Ma attacked the Norwegian government, saying that the award was given despite warning from China that such a move would damage the ties.
In support of the Nobel laureate, US President Barack Obama and several global leadrs have demanded release of Liu after was named Nobel peace prize winner.
"Politicians from some counties are using this opportunity (award) to attack China. This is not only disrespect to China's judicial system but also put a big question on their true intention," he said.
"As a responsible government, Norway is supposed to know what it should and should not do," he added.
