BEIJING, Sept. 6 (Xinhua) -- China will launch a project joined by seven municipalities, provinces and an autonomous region to build a security "moat" to keep its capital city safe during the People's Republic's 60th National Day celebrations.

    Beijing, Tianjin, Hebei, Shanxi, Shandong, Liaoning and Inner Mongolia Autonomous Region have signed an agreement on the project, said Chen Jiping, deputy director of the Central Committee for Comprehensive Management of Public Security, on Sunday.

    According to the agreement, the authorities of these municipalities, provinces and regions will conduct security checks on roads to Beijing to fence off the potential threats. The neighboring provinces will also work out a system to tackle discord at home turf to prevent local residents to lodge complaints in the capital city. The police will cooperate to contain crimes crossing provincial borders. The agreement also said that the governments will tighten the control over dangerous objects and better regulate the flow of migrant population.

    With the National Day less than a month away, the authorities in the seven provinces and regions must strengthen cooperation and work closely together to ensure the smooth operation of celebrations, said Chen Jiping, vice-director of the committee.

    China will hold a huge gathering in Tian'anmen Square on Oct. 1 when Chinese President Hu Jintao will give a keynote speech. A military parade and mass pageant will follow and proceed along Chang'an Avenue.
