China's northeast Heilongjiang Province will build a park in 2010 to mark the Japanese Unit 731's notorious experiments during its aggression of China from 1937 to 1945, said local authorities.

The park will be based on the zone of the unit's ruins in Pingfang District, Harbin City, capital of Heilongjiang, the Harbin Municipal Government said.

Unit 731 was a covert biological warfare research and development center operated by Japanese invaders during its war of aggression. It conducted vivisections and other inhumane atrocities on Chinese prisoners of war.

A museum built on the ruins opened to the public on August 15, 1985. The museum includes a hall of evidence of Japan's crimes and 23 ruins.

Relocation of companies and residents for construction of the park began in November 2009.
