BEIJING, Dec. 22 -- The reform of a UNESCO heritage listing should reflect the broad will of its member states and avoid being politicized by any particular country, Chinese Foreign Ministry spokesperson Hong Lei said on Tuesday.

Hong's comment came after UNESCO was reportedly "reviewing guidelines for the listing system" of the Memory of the World, after Japan called for improvement following the registration of China's "Documents of Nanjing Massacre" in October.

"(The proposed) reform should be based on extensive solicitation of views from member states and their consensus," Hong said.

He added that if a particular country intends to politicize the reform and even takes advantage of the reform to deny or glorify its history of aggression, the international community will resolutely oppose it.

Memory of the World Programme was established by UNESCO in 1992 for the preservation of documentary heritage.
